Symfony 2 Benchmarking Test

The information below contains information specific to Symfony2. For further guidance, review the documentation. Also note the additional information provided in the PHP README.

This is the Symfony 2 PHP portion of a benchmarking test suite comparing a variety of web development platforms.

Infrastructure Software Versions

The tests were run with:

• Symfony Version 2.2.1
• PHP Version 5.5.17 with FPM and APC
• nginx 1.4.0
• MySQL 5.5.29

Paths & Source for Tests

• JSON Serialization
• "/json" Note: Uses the PHP standard JSON encoder.
• Single Database Query (Model)
• "/db" Note: Uses the Symfony 2/Doctrine 2 Entity functionality.
• Multiple Database Queries (Model)
• "/db?queries=" Note: Uses the Symfony 2/Doctrine 2 Entity functionality.
• Fortunes Template Test
• "/fortunes" Note: Uses Symfony's template engine 'Twig'

Advice for Adding Symfony2 Tests

This implementation is the direct result of installing the Standard Edition of Symfony 2 using Composer, and making the minimum modifications necessary to support running the benchmark. Specifically, unnecessary bundles have not been removed from the kernel to properly reflect "out of the box" performance. If you're interested in tuned performance, see the symfony-stripped test, which removes and unnecessary components.

Note: app/bootstrap.php.cache is generated by Composer when you first run composer.phar install
