[go-nuts] Re: Can't explain Golang benchmarks

Awesome :) got similar results. So channels are slower for pubsub. I am surprised so far, with the efficiency going down as the cores go up (heck reminds me of that Node.js single core meme). Please tell me I am wrong here, is there any other more efficient approach? On Sunday, July 16, 2017 a

The active work for Go2 right now is gathering experience reports . Most of the changes resulting from these reports will land in Go1.x. It is expected that Go2 will only have a few major changes that will not be compatible with Go1. It is also possible

Hi Tong, Glad to see you're finding gojson useful. Let us know if you have suggestions; if there are improvements which would be helpful for people in general, we'd be happy to merge them upstream. On Sunday, July 16, 2017 at 10:28:09 AM UTC-4, Tong Sun wrote: > > Hi, > > I've started to impr

Your latest benchmarks are invalid. In your benchmarks, replace b.StartTimer() with b.ResetTimer(). Simply run benchmarks. Don't run race detectors. Don't run profilers. For example, $ go version go version devel +504deee Sun Jul 16 03:57:11 2017 + linux/amd64 $ go test -run=! -bench=. -ben

Thanks for pointing issues out I updated my code to get rid of race conditions (nothing critical I was always doing reader-writer race). Anyhow I updated my code on https://gist.github.com/maxpert/f3c405c516ba2d4c8aa8b0695e0e054e. Still doesn't explain the new results: $> go test -race -run=!
