| 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 | |
