| ==== OS X ==== | ==== macOS ==== |
| There's a bug in older versions of OS X which prevents getting good results from the profiler. There's a (scary) way to fix this by [[https://godoc.org/rsc.io/pprof_mac_fix| binary patching the OS X kernel]] (I've used it, it worked, but no guarantees at all). | There's a bug in older versions of macOS(or OS X) which prevents getting good results from the profiler.

| There are many additional options in gperftools and while I found the above sufficient for profiling Geany, there may be cases where some extra parameter may be necessary (such as filtering the graph to some subset, more frequent sampling, etc.). See the CPU profiler [[http://gperftools.googlecode.com/git/doc/cpuprofile.html| documentation]] for more info. | There are many additional options in gperftools and while I found the above sufficient for profiling Geany, there may be cases where some extra parameter may be necessary (such as filtering the graph to some subset, more frequent sampling, etc.).
