Great content. Nice work to make a very technical topic into an interesting, engaging, and entertaining talk.

Fun and engaging talk with a nice overview of methods for tracking down bottlenecks.

Good use of a specific codebase example to relate to issues that many of us might face.

It was a great way to walk through the problems being faced and the steps taken to solve them

Great insights to help diagnose where your code is running slowly. Starting from the basics and then headed into the technical, it was great to see how the tools had helped in a real life situation.

Good talk. Particularly liked talk about use of profiling/cachegrind and XHPROF. Good slides ;)

This was a great extended commentary on moving beyond petty debates on the relative speed of certain actions (e.g. echo vs. print) and how to deal with large scale slow downs using logging and advanced analytical tools. The use of a specific case study was very helpful in visualizing this process.
