Sorry, I think the change I was thinking of was macOS specific, and in any case it’s in Go 1.10.

After I benchmark time.Now on my computer, I found that the time.Now takes about 3758 ns to perform one operation, which is not very fast. The benchmark is here<https://gist.github.com/reinit/82608ab20e5aac3bd3c1eb5a8f78d23c> (benchmarked on my Ubuntu 18.04 LTS machine). So, I want to know is that normal to be this slow? If it is (slow), then does there is an alternative way to to that? Thank you! -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
