Benchmarking using the supplied Docker Stack

Use the supplied Docker Stack in order to automatically set up the following benchmarking environments:

Ubuntu 15.04 64bit (Docker)
- PHP-FPM 5.6.4
  - Zend OPcache 7.0.4-dev
  - PhalconPHP 2.0.9
- HHVM 3.10.1

By sharing underlying software stacks, the benchmark results vary only according to the host machine's hardware specs and ORM implementations.

Cd into the .docker-stack directory of this repo and make sure that docker toolbox is available:

cd .docker-stack
eval "$(docker-machine env default)"

Run benchmarks using PHP 5.6.4:

docker-compose run shell
php TestRunner.php

Run benchmarks using HHVM 3.10.1:

docker-compose run shell
/usr/bin/update-alternatives --install /usr/bin/php php /repo/.docker-stack/stack/php/hhvm-jit.sh 60
php TestRunner.php

Run benchmarks using PHP 7.0.0:

docker-compose run shell_php7
php TestRunner.php
