crypto/sha256: add native SHA256 instruction implementation for AMD64 · Issue #50543 · golang/go
The sha_ni sha256 instructions have been shown to provide an ~4x increase in hash rate on newer amd64 systems versus the avx2 implementation. Transliterating the Linux implementation shows an up to...

Optimizing GoAWK with a bytecode compiler and virtual machine
How I sped up GoAWK by switching from a tree-walking interpreter to a bytecode compiler and virtual machine interpreter.

Go performance from version 1.2 to 1.18
Shows how much the performance of Go has improved from version 1.2 through to 1.18 -- in its compiler, runtime, and libraries.
Okay – took the nerd snipe bait – here is a little package to add cpu-ns/op to any bench function.

User Zik have combined and benchmarked @bboreham patches related to the #golang regexp package and...results are astonishing!
Well, if all these patches will be merged in 1.19 we can get 30-40% better perf!

Sen Han created an issue about Completely Fair Scheduler inspired for #golang https://github.com/golang/go/issues/51071 + demo https://github.com/hnes/cpuworker
Keep in mind: it's just an interesting prototype now and there is no official plans to change the current scheduler.

Aaaaand after somewhat heated discussions in chats upcoming #golang generics will not allocate interfaces. But looks like this will be available only in Go 1.19... issue https://github.com/golang/go/issues/50182 and fix https://go-review.googlesource.com/c/go/+/378178/
Good new everyone, there are fixes for issue about performance of the generics, but anyway we will wait for #golang 1.19
