Recently at work I was involved a project which aimed to improve the performance of one of our analytics systems. We needed a way of measuring our progress of certain user flows before and after optimization so we could give the client feedback on how the project was progressing.

Blackfire is a performance measuring tool written by the folks behind the symfony php framework and was ideal for the task. You can read about my experience with blackfire over on the Box UK dev blog.
