This package allows you to report On-CPU Time in addition to the wall time measured by Go's builtin benchmarking framework. Example:
import "github.com/felixge/benchmore"
func BenchmarkAdd(b *testing.B) {
defer benchmore.ReportCPUTime(b)()
for i := 0; i < b.N; i++ {
Add(i, i)
}
}
func Add(a, b int) int {
return a + b

This package was created as a quick proof of concept response to a tweet by @bwplotka.
In the future it could be extended to capture other metrics such as heap, rss, context switches, etc.
