 This version of Imageflow was used: https://github.com/imazen/imageflow/commit/80d38f8c471d60a89dfebe9543fb364b99c7743e
 The benchmark script is here: https://github.com/imazen/imageflow/blob/80d38f8c471d60a89dfebe9543fb364b99c7743e/wrappers/server/bench_single_thread.sh

 ./bench_single_thread.sh 
 This benchmark is for ubuntu 14.04. 
 Please run the following commands first for more accurate results
 mkdir bench_in
 mkdir bench_out
 sudo mount -t tmpfs -o size=512M tmpfs bench_in
 sudo mount -t tmpfs -o size=512M tmpfs bench_out

 You may also need to sudo apt-get install parallel
 and sudo apt-get install linux-tools-common linux-tools-generic

 on OS X, you will need to edit this script to use time instead of perf stat
