Really good overview on how to utilize profiling and the performance improvements you can get from relatively minor changes.

An interesting topic that was delivered in a measured way which made it easy to understand and follow along. Some good thoughts at the end about judging if you should profile or not.

Another clear and well paced talk from Michael.

I have always had problems knowing where to start with improving code performance and this talk has answered a ton of questions I've had rolling around in my head.

He showed the problem and then lead us through the thought process of how to find the solution by trying the obvious solution, and then testing that assumption against the data. It was great to sit in the talk and have my assumptions challenged, I also learnt a few new functions and some new things about functions I thought I knew well!

Excellent talk. The real strength of Michael's style is to make you realise there's no black art knowledge or guru status needed to make a real difference to your app performance - just a few free tools and an inquisitive brain - his passion for the subject comes across well and should inspire us all to get better at profiling.

A really great introduction to profiling, and the tools available to the community

Great talk and very interesting. It's always nice hearing a talk with a real world example. It was a nice touch mentioning xhprof as well as Blackfire and the advantages/disadvantages of both. I think somebody raised a point about blackfire being free to use with some paid premium features. all in all, great talk and lots of improvements since you gave the talk at PHPSW.

Profiling of production. Profiling your tests. Using extra machines to save dev refactoring time. Very helpful practical ideas.
