Help my client is complaining some parts of the application are slow. Now what?


What is profiling and how can we measure the performance of our application? There are several tools we can use. Once we have the tools, how do we approach profiling. What to look for. And caveats to avoid when profiling. To finish up, we should avoid that our client is complaining about performance, how can we pro actively use profiling to improve our application.

When finished we will end up with a nice toolbox of profiling tools and good ideas how to do profiling and avoid some common mistakes that might distract you from the real opimisation.

Good overview of profiling tools available, nice pace, demo that worked, can’t really ask for more.

Great talk. Understandable demo. Some New Relic examples in slides would have been nice

Interesting talk and a nice demo. I have to give xhprof a new chance now

Quite interesting talk about profiling tools and practice. An example was also interesting.

Profiling with xhprof and some nice visualizations. It is always a good idea to revisit knowledge like that. I didn't know FlameGraph before.
