Nice and brief introduction. Thanks for useful tools :)
Profiling PHP Applications
Derick Rethans (22.Oct.2011 at 11:00)
Talk at PHPCon Poland 2011 (English - UK)
The web is full of useful advice focussed on pushing out the last bit of performance of your code. They mention trivial changes. like changing every occurrence of print with echo even suggesting to use for instead of foreach. These optimisations help, but you are not going to notice it unless they're in a tight loop with many iterations. It is also a wrong approach for tackling performance issues. Before you can optimise, you need to find out if your code is actually slow; then you need to *understand* the code; and *then* you need to find out where you can optimise it. This talk introduces tools and concepts to optimise the optimisation of your PHP applications.

I was expecting a very good presentation and I was not disappointed. I liked that Derick focused not only on XDebug, but approached the topic very maturely presenting a range of techniques and tools possible to use.

This guy knows what he is talking and doing it in a great way. I knew some of the techniques, but a few things was new for me. Well presented with live demos, great talk.
