Simple benchmark for Symfony2

README.md

You should download each of the three versions of Symfony2 in /var/www/benchmark/sf2<X> where <X> is the minor version. Then

chmod +x benchmark.sh
sudo ./benchmark.sh

AB output for each run will be found in /var/www/benchmark/results/

Note

This was tested only with Ubuntu 12.10, your folders/URLs may vary

Also, I didn't want to push this to hardware limits as this shouldn't be a question of how many but rather how fast. If it's fast enough, the rest will follow.

Sleeps are there to allow for your hardware/CPU to catch its breath, this really is not a hardware test :)
