  go pprof
  I have a service written in go that takes 6-7G memory at runtime (RES in top). So I used the pprof tool trying to figure out where the problem is.go tool pprof –pdf http://<service>/debug/pprof/heap > heap_prof.pdfBut there are only about 1-2G memory in result (‘Total MB’ in pdf). Where’s the rest ?And I’ve tried profile my service with GOGC=off, as a result the ‘Total MB’ is exactly the same as ‘RES’ in top. It seems that memory is GCed but haven’t been return to kernel won’t be profi

  google-perftools pprof heap-profiling
  We’re using google-perftools heap profiler in a TDD environment. We get the heap dump at the end that we can use pprof to see the hot spots.

In fact, there’s no organization in the output that I can see whatsoever.The stack trace of the largest leak is displayed at runtime but does not show any symbols. We’re correctly setting the PPROF_PATH environment variable but it’s not having any effect. How

  go profiling pprof
  I have a small program in go that executes most of its code in parallel using go routines. I start CPU profiling as described in the blog on profiling go programs, but when I look at the data I see only 3-5 samples (the actual runtime of the program is several seconds). Is there way to increase the sample rate? Tried googling but couldn’t find a thing…
