QCachegrind helps you profile the performance of your open source applications. You can use it together with Xdebug and CommunityPlus+ PHP to determine exactly where your application lags, as well as how much time and memory it consumes in problem areas.
There’s no more guesswork in measuring performance. Instead, you can scientifically compare programming approaches.
Check out our tutorial on the best way to get started with measuring application performance with Xdebug and QCachegrind.
QCachegrind is free software developed by KDE‘s community of open source developers. Seiden Group provides ready-to-use builds for Windows and macOS, and the expertise to integrate it into your workflow. We also contribute our enhancements back to the community.
Even on a small script, you can see where execution time and memory allocations happen.
