When choosing a web framework, I pretty much have eyes set on Tornado. But I heard good things about Flask and Gevent. So I tested the performance of each and combinations of the three. I chose something just a little more advanced than a "Hello World" program to write - one that use templates. Here are the codes:
| #!/usr/bin/python | |
| import sys | |
| import subprocess | |
| data = sys.stdin.read() | |
| _, new_obj, _ = data.split() | |
| def command_output(command): | |
| output = subprocess.check_output( |
| import redis | |
| import threading | |
| class Listener(threading.Thread): | |
| def __init__(self, r, channels): | |
| threading.Thread.__init__(self) | |
| self.redis = r | |
| self.pubsub = self.redis.pubsub() | |
| self.pubsub.subscribe(channels) | |
| import os | |
| import sys | |
| import fcntl | |
| import gevent | |
| from gevent.socket import wait_read | |
| def print_every(s, repeat=1): | |
| print s | |
| if repeat: |
| package main | |
| // run with: $ go test --bench=. -test.benchmem . | |
| // @see https://twitter.com/karlseguin/status/524452778093977600 | |
| import ( | |
| "math/rand" | |
| "strconv" | |
| "testing" | |
| ) |
| var itemExists = struct{}{} | |
| type Set struct { | |
| items map[interface{}]struct{} | |
| } | |
| func New() *Set { | |
| return &Set{items: make(map[interface{}]struct{})} | |
| } |
| package main | |
| import ( | |
| "bufio" | |
| "net" | |
| ) | |
| type Client struct { | |
| incoming chan string | |
| outgoing chan string |
