Hello!
Recently I read some go source code and when I read the noescape function
in runtime/stubs.go, I have a doubt about it.
// noescape hides a pointer from escape analysis. noescape is
// the identity function but escape analysis doesn't think the
// output depends on the input. noescape i
Is this operation necessary?

Hi!
We have a go program (an api server) on a virtual machine(with 8 cores)
with a long time stable running.
However, the program recently suffered a weird problem that only a single
CPU reached 100%
usage while others were very low, in the meanwhile, the network bandwidth
was totally zero,

Thanks for you reply.
