How did you generate the GC pause graphs? Could also provide the output from "GODEBUG=gctrace=1 yourApp"? It would help confirm that it is a GC pause problem. Also some insight into the number of cores / HW threads and the value of GOMAXPROCS could eliminate some possibilities. A reproducer would be great. Thanks in advance.
