Profiling Your PHP Application

I've always been curious as to how to determine what was taking so long, and where that was. I really appreciate that you took the time to explain the options I have and what they look like.

Excellent talk. Examples were very well done and easy to follow. Did a great job of covering a lot of information and answering questions.

Great advice on profiling, mainly using XHProf. As someone who has used this tool, I enjoyed the examples and the learned about some features of which I was not previously aware. Michael also referenced some additional tools that I'm looking forward to trying out.

Any talk where you get concrete examples and learn something real are sometimes hard to find. This talk was focused and demonstrated the value of a specific tool. Michael was clear and obviously well prepared. I just wish he would've talked more about PHP bench! Like how to run in production.

Much like Michael's talk on logging, his talk here was equally well presented. As to topic, as taken directly from my session notes... "This is neat nerdy stuff!!".

That said, would really help to have the speaker deck posted. Thanks.

If you need to push php performance at the individual algorithm level, this was a good talk. Most people aren't going to be doing this level of optimization, though. I did like the comment about "premature optimization being the root of all evil" but don't think the presenter did a great job at answering that. Basically, I feel like this was a good talk about optimization but didn't really go into why you would care about doing it.

This talk was a voice of experience with concrete examples and sensible use cases. Everything a talk should be. I now know of new tools to explore. Talks like this are the reason to come to PHP Tek.
