The web is full of advice focussed on improving performance. Before you can optimise however, 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 what you can optimise. This talk introduces various tools and concepts to optimise the optimisation of your PHP applications.

Very well done and pointed out some things of kkachegrind which I never tried before.
Thank you!

Thanks a lot for this interesting talk Derick! If you want to improve the talk, I would rather remove a few slides on old and not really useful tools, and elaborate a bit on how the tracing and profiling works and what implications this has.
Oh and thanks for remembering me that KCacheGrind is much better than WinCacheGrind which I usually use ;)

The session was pretty good. Motivated me to give XHProf another try after I failed last time I tried it.

Nice presentation about what profiling really is and works. As Fabian I would remove some slides (maybe those about frameworks, you can just say it during talk) and do some more activity on tracing a real slow part of an application (e.g. put some ugly code somewhere) and then spot it.

Good overview over the existing tool and how to use them properly

Very Good!
