Performance Profiling, Testing and Static Analysis

[edmondscommerce]

We need to have some kind of tooling for development purposes which can provide information on performance issues and bottlenecks

We also need to extend the tests to ensure that this profiling works and also perhaps have tests that actually actively check client project for doctrine based performance issues

Finally, we should extend the PHPQA based static analysis to actively check for performance (and other) problems
