What version of Go are you using (go version)?

$ go version
go version go1.13.10

In the container, the golang process used 100% of the CPU. When I took a 5minutes CPU profile, the result shows that only 1.64mins (32.69%) samples are returned. Is it normal?

go tool pprof autoscaler_cpuprofile.out
File: autoscaler
Type: cpu
Time: Jun 29, 2020 at 11:21pm (CST)
Duration: 5.01mins, Total samples = 1.64mins (32.69%)
