thanks for response. i am using the version is go1.7, i do not know it's detail version. yes, i have profiled my program,the cpu profile,16-core cpu and 8-core cpu both done.the percent of the same functions almost at the same,but the total cpu.this is interesting.
i will follow your suggestion,use the Go 1.7.3 to see what will be happened. 在 2016年11月25日星期五 UTC+8上午6:43:04，Dave Cheney写道： > > I'm sorry you're having problems. > > Before we can help you need to help us by giving us details. > > - Which version of Go are you using?
