--- Comment #1 from Milian Wolff <m...@milianw.de> --- The short living threads are used by libclang for crash resilience. You can verify whether that really is the problem by temporarily disabling that feature. For that, you will need to recompile KDevelop though, and add a call to `clang_toggleCrashRecovery(false)`, e.g. in `kdevelop/language/clang/duchain/clangindex.cpp`, before the call to `clang_CXIndex_setGlobalOptions`. That said, I doubt that this is the reason for the high CPU usage. Could you please use a profiler to get some hard data? - install debug symbols for kdevelop + kdevplatform - profile CPU with perf: perf record --call-graph dwarf --pid $(pidof kdevelop) # wait a couple of seconds while kdevelop has high CPU usage # ^C -> this stops the record and writes a `perf.data` file then run perf report --no-children -g graph | bzip2 > perf.report.bz2 and upload the report here. -- You are receiving this mail because: You are watching all bug changes.
