[go-nuts] Profiling goroutines

[jason.桂林]

At the end of the blog http://blog.golang.org/profiling-go-programs said:

    "The goroutine blocking profile will be explained in a future post. Stay tuned."

I searched, can not found that "future post".

I've also just found that and searched, and the best thing I found was your post, Jason. I'd love to know more!

Brad gave a talk about profiling:
https://github.com/bradfitz/talk-yapc-asia-2015/blob/master/talk.md
He runs out of time so there is just a very quick example of how to use the block profiler.
Should be enough to get you started though, it's similar to CPU profiling, it's the same tool.

I've filed https://github.com/golang/go/issues/14689 since it really seems like an issue that documentation on this is not easy to find.

Along the way I did eventually find https://software.intel.com/en-us/blogs/2014/05/10/debugging-performance-issues-in-go-programs which seems to be a useful resource. Unfortunately it was not timely though.
