in addition to the original question, I have found a way to get the following memstats in a few seconds:
# runtime.MemStats # Alloc = 22267160 # TotalAlloc = 42133760 # Sys = 8852177152 # Lookups = 0 # Mallocs = 1041166 # Frees = 805749 # HeapAlloc = 22267160 # HeapSys = 67108864 # HeapIdle = 42459136 # HeapInuse = 24649728 # HeapReleased = 41943040 # HeapObjects = 235417 # Stack = 0 / 8778907648 # MSpan = 384064 / 393216 # MCache = 5016 / 16384 # BuckHashSys = 1452992 # GCSys = 3676424 # OtherSys = 621624 # NextGC = 27397520 # LastGC = 1627069277209120125 7 threadcreate 7 goroutine Total allocations of golang program are about 42MB, but go runtime takes 8GB for in OS thread stacks. What am I doing wrong? Thanks!
