Just a short note on that: Most of the actual work in RRDCacheD is done in threads. gprof is not able to handle that very well (basically not at all). > It looks to like that's mostly the journal replay stuff and very little > more. Journal replay is done during startup in the main thread, so gprof is able to grab information about that but probably misses about everything else. You might want to have a look at callgrind, which is one of the valgrind tools that may be used for call graph tracing and which supports multi- threaded programs as well.
