    ### Whats next
    I will be upgrading to HHVM 3.3 and re-running the tests later in the week. I couldn't find a repo that contained HHVM 3.3 so I may build from source. Like I said if you find any inconsistancy I'm open to trying to tune further or make changes in my config.



    --------------------------------

    ### Working around incompatabilities with HHVM
    Let's say you have an extension that is Ioncube encoded. I'm looking at your Unirgy :) You want it to work but it can't use HHVM or lets say you have an issue with an incompatiable SOAP call or PHP extension. You can get around the issues by tricking out your Nginx configuration to serve pages that are of certain URI on PHP instead of HHVM. Here is an example:

    ```nginx
    location ~ \.php$ { ## Execute PHP scripts
    if (!-e $request_filename) { rewrite / /index.php last; }
    set $use_hhvm 1;
    if ($request_uri ~ ^/(index.php/admin/sales_order|index.php/urapidflowadmin)) {
    fastcgi_pass 127.0.0.1:9000;
    set $use_hhvm 0;
    }
    expires off; ## Do not cache dynamic content
    if ($use_hhvm = 1) {
    fastcgi_pass unix:/var/run/hhvm/sock;
    }
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params; ## See /etc/nginx/fastcgi_params
    fastcgi_keep_conn on; #hhvm param
    }
    ```

    As you can see I used a pipe "|" beween the URLS I want to use plain PHP.

I would be happy to further tune my PHP configuration if needed but it looks like PHP 7 and HHVM 3.2 and really close! Great work by both teams.

    ```
    # remove any existing PHP installations
    sudo yum remove php*
    ```
    ###### Install correct version of bison
    Since the distro package of bison1 isn’t the correct version, you need to build it from source.
    ```bash
    mkdir ~/tmp
    cd ~/tmp
    wget http://ftp.gnu.org/gnu/bison/bison-2.4.tar.gz
    tar -xzf bison-2.4.tar.gz
    cd bison-2.4
    ./configure
    make && make install
    cd ../
    ```

    ###### Install pre-reqs:
    ```bash
    yum install -y bzip2-devel curl-devel libjpeg-devel libpng-devel libXpm-devel gmp-devel libc-client-devel freetype-devel t1lib-devel.x86_64 libmcrypt-devel.x86_64 recode-devel libxml2-devel mysql-devel aspell-devel
    ```

    # Zend Engine v2.8.0-dev, Copyright (c) 1998-2014 Zend Technologies
    ```

    ###### Create (Copy over) the PHP-FPM startup script that comes with the PHP source.
    ```bash
    sudo cp ~/tmp/php-src/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
    chmod 755 /etc/init.d/php-fpm
    ```

    ###### Edit the defaults:
    ```bash
    vi /etc/init.d/php-fpm
    ```
    ```

    php_fpm_PID=/var/run/php-fpm.pid
    ```

    ###### Copy over the PHP-FPM config
    Make any edits you need to php-fpm.conf file. By default it listens on port 9000.
    ```bash
    mv /usr/local/etc/php-fpm.conf.default /usr/local/etc/php-fpm.conf

    ##### Apache JMeter Benchmarking
    Magento has release a beta version of performance testing scripts that are available [here](https://github.com/magento/magento-performance-toolkit). I followed the instructions in the accompanying PDF document, but had some troubles when I was trying to run the JMeter script on my local OSX machine. Magento doesn't mention it in the documentation but you also need to add the [JMeter plugins](http://jmeter-plugins.org).

    Or you can use the GUI version of JMeter and get the fancy charts and graphs. You just need to enable the charts and set the paramters. I'm a rookie at JMeter so I'm sure I have lots to learn.

    I've had the opertunity to try a variety of different server configurations but never really got around to trying HHVM with Magento until recently. I thought I would share a detailed walkthrough of configuring a single instance Magento server running Nginx + Fast CGI + HHVM / PHP-FPM + Redis + Percona. For the purpose of this blog post I'm assuming you are using Fedora, CentOS, or in my case RHEL 6.5.

    #### Install the EPEL, Webtatic, and REMI repos

    rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm
    ```

    #### Install PHP 5.5.18
    ```bash
    yum -y install php55w php55w-opcache php55w-devel php55w-mcrypt php55w-gd php55w-mbstring php55w-mysql php55w-pdo php55w-soap php55w-xmlrpc php55w-xml php55w-pdo php55w-mysqli libwebp
    ```


    #### Install Percona
    Note you may have existing mysql packages installed in your distro. If you do you will need to remove them prior to installing Percona. You can check by issuing:
    ```bash
    rpm -qa | grep -i mysql
    ```
    For instance on my server I needed to remove the following:
    ```bash
    yum remove mysql
    yum remove mysql-libs
    yum remove compat-mysql51
    ```

    ###### Setup the Percona Repo
    Open a VI editor to the following file.
    ```bash
    vi /etc/yum.repos.d/Percona.repo
    ```
    Add the following:
    ```
    [percona]
    name = CentOS $releasever - Percona
    baseurl=http://repo.percona.com/centos/$releasever/os/$basearch/
    enabled = 1
    gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-percona
    gpgcheck = 1
    ```

    ###### Grab the Percona GPG key
    ```bash
    wget http://www.percona.com/downloads/RPM-GPG-KEY-percona
    sudo mv RPM-GPG-KEY-percona /etc/pki/rpm-gpg/
    ```

    ###### Install Percona via Yum
    ```bash
    sudo yum install -y Percona-Server-client-56 Percona-Server-server-56 Percona-Server-devel-56
    ```

    ###### Start Percona and Setup Root Pass
    ```bash
    service mysql start
    # then run
    /usr/bin/mysql_secure_installation
    # setup root password
    ```


    #### Install HHVM

    ```bash
    # needed to work around libstdc version issue
    sudo yum upgrade --setopt=protected_multilib=false --skip-broken

    # setup the hop5 repo
    cd /etc/yum.repos.d
    sudo wget http://www.hop5.in/yum/el6/hop5.repo

    # show available versions of hvvm
    yum list --showduplicates hhvm

    # install latest verison show from list above
    yum --nogpgcheck install -y hhvm-3.2.0-1.el6
    ```

    #### Install Nginx and PHP-FPM
    ```bash
    yum --enablerepo=remi install -y nginx php55w-fpm php55w-common
    ```


    #### Configuring Nginx
    ```bash
    # rename the default config as its not needed
    sudo mv /etc/nginx/conf.d/default.conf /etc/nginx/conf.d/default.conf.old

    # create a new config
    vi /etc/nginx/conf.d/server.conf
    ```

    ```nginx

    }
    # Server
    include main.conf;
    include security.conf;
    }
    ```

    #### Create a home for your website
    If you don't already have a place for your website files to live you will need to create one:
    ```bash
    sudo mkdir -p /var/www/mysite/

    # while you at it create a nice static error page
    echo "error page" >> /var/www/sites/hvvm/504.html
    ```

    #### Setup Nginx for HHVM and Magento
    Nginx needs to be told how to work with PHP traffic and forward it via FastCGI to HHVM. Here is a good configuration. You will notice their is some standard rewrites for Magento assets in place.

    ```bash
    vi /etc/nginx/main.conf
    ```
    ```nginx
    rewrite_log on;
    location / {
    index index.php;
    try_files $uri $uri/ @handler;
    }
    location @handler {
    rewrite / /index.php;
    }
    ## force www in the URL
    if ($host !~* ^www\.) {
    #rewrite / $scheme://www.$host$request_uri permanent;
    }
    ## Forward paths like /js/index.php/x.js to relevant handler
    location ~ \.php/ {
    rewrite ^(.*\.php)/ $1 last;
    }
    location /media/catalog/ {
    expires 1y;
    log_not_found off;
    access_log off;
    }
    location /skin/ {
    expires 1y;
    }
    location /js/ {
    access_log off;
    }
    location ~ \.php$ { ## Execute PHP scripts
    if (!-e $request_filename) { rewrite / /index.php last; } ## Catch 404s that try_files miss
    expires off; ## Do not cache dynamic content
    # for this tutorial we are going to use a unix socket
    # but if HHVM was running on another host we could forego unix socket
    # in favor of an IP address and port number as follows:
    #fastcgi_pass 127.0.0.1:8080;
    fastcgi_pass unix:/var/run/hhvm/sock;
    fastcgi_index index.php;
    #fastcgi_param HTTPS $fastcgi_https;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    # if you need to explictly specify a store code for Magento do it here
    # this is useful if you are running multiple stores with different hostnames
    #fastcgi_param MAGE_RUN_CODE default;
    #fastcgi_param MAGE_RUN_TYPE store;
    include fastcgi_params; ## See /etc/nginx/fastcgi_params
    fastcgi_keep_conn on; #hhvm param
    }
    ```

    Next we need to setup our security configuration:
    ```bash
    vi /etc/nginx/security.conf
    ```

    ```nginx
    ## General Magento Security
    location /app/ { deny all; }
    location /includes/ { deny all; }
    location /lib/ { deny all; }
    location /media/downloadable/ { deny all; }
    location /pkginfo/ { deny all; }
    location /report/config.xml { deny all; }
    location /var/ { deny all; }
    ## Disable .htaccess and other hidden files
    location /\. {
    return 404;
    }
    ## Disable all methods besides HEAD, GET and POST.
    if ($request_method !~ ^(GET|HEAD|POST)$ ) {
    return 444;
    }
    ```

    ### HHVM Configuration
    ```bash
    vi /etc/hhvm/server.hdf
    ```

    ```
    PidFile = /var/run/hhvm/pid
    Server {
    Port = 8080
    SourceRoot = /var/www/mysite
    DefaultDocument = index.php
    }
    Log {
    Level = Warning
    AlwaysLogUnhandledExceptions = true
    RuntimeErrorReportingLevel = 8191
    UseLogFile = true
    UseSyslog = false
    File = /var/log/hhvm/error.log
    Access {
    * {
    File = /var/log/hhvm/access.log
    Format = %h %l %u % t \"%r\" %>s %b
    }
    }
    }
    Repo {
    Central {
    Path = /var/log/hhvm/.hhvm.hhbc
    }
    }
    #include "/usr/share/hhvm/hdf/static.mime-types.hdf"
    StaticFile {
    FilesMatch {
    * {
    pattern = .*\.(dll|exe)
    headers {
    * = Content-Disposition: attachment
    }
    }
    }
    Extensions : StaticMimeTypes
    }
    MySQL {
    TypedResults = false
    }
    ```

    #### HHVM Fast-CGI support
    HHVM will need to start with Fast-CGI support so Nginx can forward PHP request to it. We also need to edit the start up script to make HHVM use a unix socket. To do this edit the following file:
    ```bash
    vi /etc/init.d/hhvm
    ```
    I've only made a few changes to the start function start function to enable zend sorting per Dan Sloofs (https://github.com/danslo) recommendation. I've also change the shutdown to kill the proper pid file (/var/run/hhvm/hhvm.pid). Here is the full init file:
    ```bash
    #!/bin/bash
    #
    # /etc/rc.d/init.d/hhvm
    #
    # Starts the hhvm daemon
    #

    ### END INIT INFO

    . /etc/init.d/functions

    start() {
    echo -n "Starting hhvm: "
    /usr/bin/hhvm --config /etc/hhvm/server.hdf --user apache --mode daemon -vServer.Type=fastcgi -vServer.FileSocket=/var/run/hhvm/sock -vEval.EnableZendSorting=1
    touch /var/lock/subsys/hhvm
    }

    stop() {
    echo -n "Shutting down hhvm: "
    killproc -p /var/run/hhvm/pid
    rm -f /var/lock/subsys/hhvm
    }

    case "$1" in
    start)
    start
    ;;
    stop)
    stop
    ;;
    status)
    if [ ! -f /var/run/hhvm/pid ]; then
    echo "hhvm not is running"
    else
    echo "hhvm is running"
    fi
    ;;
    restart)
    stop
    start
    ;;
    reload|condrestart|probe)
    echo "$1 - Not supported."
    ;;
    *)
    echo "Usage: hhvm {start|stop|status|reload|restart[|probe]"
    exit 1
    ;;
    esac
    exit $?
    ```


    #### Starting HHVM
    As you can see if the init file for HHVM we started it with the user "apache". So before starting HHVM make sure the directory your files are stored is owned by that group.
    ```bash
    sudo chown apache:apache /var/www -R
    ```
    We also need to give HHVM the permissions to:
    ```bash
    mkdir -p /var/run/hhvm
    chown apache:apache /var/run/hhvm
    chmod 775 /var/run/hhvm
    ```

    Finally we can start Nginx PHP-FPM and HHVM.

    ```bash
    service nginx start
    service php-fpm start
    service hhvm start
    ```

    The famous phpinfo() function will not work on HHVM but there is a very nice HHVM equivalent. Lets download it for fun:
    ```bash
    cd /var/www/mysite/
    wget https://gist.githubusercontent.com/ck-on/67ca91f0310a695ceb65/raw/hhvminfo.php
    ```

    SCREENSHOT HERE


    #### HHVM admin
    HHVM has an admin tool you can use to get stats. (http://hhvm.com/blog/521/the-adminserver) If you want to see what is available you can create the following file:
    ```bash
    vi /etc/nginx/conf.d/admin.conf
    ```
    ```nginx
    server {
    # hhvm admin
    listen 8889;
    location ~ {
    fastcgi_pass 127.0.0.1:8888;
    include fastcgi_params;
    }
    }
    ```

    Then add this block to your hhvm configuration:
    ```bash
    vi /etc/hhvm/config.hdf
    ```

    ```
    AdminServer {
    Port = 8888
    Password = mySecretPassword
    }
    ```

    #### Some additional tuning

    It is also recommended to use “pm = static” mode (instead of “pm = dynamic”) if you decide to
    dedicate a server for PHP-FPM exclusively, as there is no need for dynamic allocation of resources
    to PHP-FPM. The “pm” part of the configuration is more or less the same as if you were to configure
    Apache.

    #### Installing Redis
    Since we are going to be using Redis for our store lets make sure to install it.
    ```bash
    yum install -y gcc
    wget http://download.redis.io/redis-stable.tar.gz
    tar xvzf redis-stable.tar.gz
    cd redis-stable
    make
    make install

    # give Redis a home
    mkdir -p /var/redis
    ```

    #### Redis startup scripts
    We are going to be running 3 Redis instances for Magento sessions, cache, and FPC. Each redis session is on a different port. To do this we need startup scripts. Here is my startup scripts. As you can see I'm using unix sockets and allocating 500mb for sessions, 1gb for cache, and 2gb for FPC.

    ##### Sessions on port 8302

    #### Redis Startup scripts
    We need a way to start our servers. We can do this by creating startup scripts for it. Here are my 3 redis startup scripts.

    ```bash
    vi /etc/init.d/redis_8302
    ```

    ```bash
    #!/bin/sh
    #
    # redis Startup script for Redis Server
    #
    # chkconfig: - 90 10
    # description: Redis is an open source, advanced key-value store.
    #
    # processname: redis-server

    REDISPORT=8302
    EXEC=/usr/local/bin/redis-server
    CLIEXEC=/usr/local/bin/redis-cli

    PIDFILE=/var/run/redis_8302.pid
    CONF="/etc/redis/8302.conf"

    case "$1" in
    start)
    if [ -f $PIDFILE ]
    then
    echo "$PIDFILE exists, process is already running or crashed"
    else
    echo "Starting Redis server..."
    $EXEC $CONF
    fi
    ;;
    stop)
    if [ ! -f $PIDFILE ]
    then
    echo "$PIDFILE does not exist, process is not running"
    else
    PID=$(cat $PIDFILE)
    echo "Stopping ..."
    $CLIEXEC -p $REDISPORT shutdown
    while [ -x /proc/${PID} ]
    do
    echo "Waiting for Redis to shutdown ..."
    sleep 1
    done
    echo "Redis stopped"
    fi
    ;;
    *)
    echo "Please use start or stop as first argument"
    ;;
    esac

    exit 0
    ```

    ```bash
    vi /etc/init.d/redis_8402
    ```
    ```bash
    #!/bin/sh
    #
    # redis Startup script for Redis Server
    #
    # chkconfig: - 90 10
    # description: Redis is an open source, advanced key-value store.
    #
    # processname: redis-server

    REDISPORT=8402
    EXEC=/usr/local/bin/redis-server
    CLIEXEC=/usr/local/bin/redis-cli

    PIDFILE=/var/run/redis_8402.pid
    CONF="/etc/redis/8402.conf"

    case "$1" in
    start)
    if [ -f $PIDFILE ]
    then
    echo "$PIDFILE exists, process is already running or crashed"
    else
    echo "Starting Redis server..."
    $EXEC $CONF
    fi
    ;;
    stop)
    if [ ! -f $PIDFILE ]
    then
    echo "$PIDFILE does not exist, process is not running"
    else
    PID=$(cat $PIDFILE)
    echo "Stopping ..."
    $CLIEXEC -p $REDISPORT shutdown
    while [ -x /proc/${PID} ]
    do
    echo "Waiting for Redis to shutdown ..."
    sleep 1
    done
    echo "Redis stopped"
    fi
    ;;
    *)
    echo "Please use start or stop as first argument"
    ;;
    esac

    exit 0
    ```
    ```bash
    vi /etc/init.d/redis_8502
    ```
    ```bash
    #!/bin/sh
    #
    # redis Startup script for Redis Server
    #
    # chkconfig: - 90 10
    # description: Redis is an open source, advanced key-value store.
    #
    # processname: redis-server

    REDISPORT=8502
    EXEC=/usr/local/bin/redis-server
    CLIEXEC=/usr/local/bin/redis-cli

    PIDFILE=/var/run/redis_8502.pid
    CONF="/etc/redis/8502.conf"

    case "$1" in
    start)
    if [ -f $PIDFILE ]
    then
    echo "$PIDFILE exists, process is already running or crashed"
    else
    echo "Starting Redis server..."
    $EXEC $CONF
    fi
    ;;
    stop)
    if [ ! -f $PIDFILE ]
    then
    echo "$PIDFILE does not exist, process is not running"
    else
    PID=$(cat $PIDFILE)
    echo "Stopping ..."
    $CLIEXEC -p $REDISPORT shutdown
    while [ -x /proc/${PID} ]
    do
    echo "Waiting for Redis to shutdown ..."
    sleep 1
    done
    echo "Redis stopped"
    fi
    ;;
    *)
    echo "Please use start or stop as first argument"
    ;;
    esac

    exit 0
    ```

    ##### Set the file permissions on the startup scripts:
    ```bash
    cd /etc/init.d/
    chmod 755 redis_*

    mkdir -p /var/redis/8302
    mkdir -p /var/redis/8402
    mkdir -p /var/redis/8502
    chmod 775 /var/redis/8302
    chmod 775 /var/redis/8402
    chmod 775 /var/redis/8502
    ```

    ##### Starting Redis servers
    ```bash
    sh /etc/init.d/redis_8302 start
    sh /etc/init.d/redis_8402 start
    sh /etc/init.d/redis_8502 start
    ```

    You can verify it is running by using the redis-cli tool:
    ```bash
    redis-cli -p 8302
    redis-cli -p 8402
    redis-cli -p 8502
    ```


    ##### Apache JMeter Benchmarking
    Magento has release a beta version of performance testing scripts that are available here: https://github.com/magento/magento-performance-toolkit
    I followed the instructions in the accompanying PDF document, but had some troubles when I was trying to run the jmeter script on my local OSX machine. Magento doesn't mention it in the documentation but you also need to add the JMeter plugins here: http://jmeter-plugins.org/.

    When you are ready to run the benchmark simply issue:
    ```bash
    jmeter -n -t benchmark.jmx -Jhost=beepaux03.mmm.com -Jbase_path=/ -Jusers=100 -Jramp_period=300 -Jreport_save_path=./
    ```

    ###### Here are the OSX instructions for those using homebrew:
    ```bash
    brew install jmeter
    wget http://jmeter-plugins.org/downloads/file/JMeterPlugins-Standard-1.2.0.zip
    wget http://jmeter-plugins.org/downloads/file/JMeterPlugins-Extras-1.2.0.zip
    unzip JMeterPlugins-Extras-1.2.0
    yes | cp -R JMeterPlugins-Extras-1.2.0/lib /usr/local/Cellar/jmeter/2.11/libexec/lib
    yes | cp -R JMeterPlugins-Standard-1.2.0/lib /usr/local/Cellar/jmeter/2.11/libexec/lib
    ```

    If your interested the inter-workings on the Magento JMeter script there is a detailed break down here: http://www.ubik-ingenierie.com/blog/magento-performance-toolkit-and-jmeter-best-practices/

    Also to note:
    Default JMeter java configuration comes with 512 Mo and very little GC tuning. First ensure you set -Xmx option value to a reasonable value regarding your test requirements. Then change MaxNewSize option in jmeter file to respect the original ratio between MaxNewSize and -Xmx.

    ```
    vi /usr/local/Cellar/jmeter/2.11/libexec/bin/jmeter
    # change head param to increase memory
    HEAP="-Xms1G -Xmx3G"
    ```
