Very good article about VM internals: Optimizing GoAWK with a bytecode compiler and virtual machine. https://benhoyt.com/writings/goawk-compiler-vm/ #golang
And an additional post about #golang performance and binary size.

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

GopherCon 2020: Pardon the Interruption: Loop Preemption in Go 1.14 - Austin Clements
Go 1.14 significantly changed how goroutines are preempted for scheduling and garbage collection. Since Go 1.2, the Go runtime has preempted goroutines only at function calls. Most of the time, this let Go developers ignore preemption and focus on writing…

The linux/amd64 version of race runtime is submitted.
Besides removing the goroutine limit, it should also be ~2x-ish faster and consume less memory.
