By an accident have found a page where you can see all #golang perf-related issue and their progress https://github.com/orgs/golang/projects/8/views/1
As I understand it's a @github feature to have a better view of issues. Might be useful.
(no idea what it's not visible on Golang Projects tab)

Shaving 40% Off Google’s B-Tree Implementation with Go Generics - ScyllaDB
Go generics are a new way to improve performance in #golang. Let's see what effect generics had on Google's B-tree implementation.

Generic approach · Issue #41 · google/btree
With support for generics, we can replace interfaces with generic types. The use of generics avoids variables escaping to heap when calling the B-tree functions yielding 20-30% improvement. Below a...

(please, don't comment on the issue, everything will be deleted as a spam)

I hope that making this meeting public will make @golang team life easier because feedback loop will be shorter with more eyes on 1 thing.

Sometimes the only thing standing between your application and 3x better performance is a letter or two.
