# galimulator-profiler > [!IMPORTANT] > As async-profiler is only available for Linux and MacOS, this mod will refuse > to work under Windows. You can still use certain profilers like VisualVM > for your profiling needs under Windows though. A mod for Galimulator that integrates a user-friendly interface for async-profiler into Galimulator. The interface can be opened using `p`, overriding the rather primitive built-in profiler of vanilla Galimulator. There isn't much to talk about. The core functionality of this mod can also be obtained by plainly using async-profiler manually. This mod just repackages it in a way where it is nicer to use. The idea will be to add more functionality to better be able to debug lagspikes by integrating it with the core tick loop - but at the moment that is not the case.
