GopherCon 2020: Common Patterns for Bounds Check Elimination - Agniva De Sarker
Bounds checks are a necessary evil. If you don’t have them, you lose memory safety. If you have them, you hurt performance. Is it possible to have the best of both worlds? Why, yes! Watch this talk to learn more.

Neat #golang trick how to pack multiple slice allocations into one (or less than in a naive way), thanks to twitter.com/tvii for showing this!

Cool stuff: buffer pool in #golang based on databases.
Also a neat part: CLOCK Replacement algorithm (read as better LRU, LFU policy)(however better can be argued :)
Thank you twitter.com/brunocalza !

Better IP addr in #golang by twitter.com/tailscale (and twitter.com/bradfitz)
The article isn’t about performance only, but the criteria for a new type are well described https://tailscale.com/blog/netaddr-new-ip-type-for-go/

Go compiler and runtime meeting notes (https://github.com/golang/go/issues/43930)
> We discussed how to address amd64 per-architecture optimizations. Haswell specific optimizations have shown large improvements in certain workloads, and it might be worth providing for these wins. Discussion will likely continue.
Also see:
cmd/compile: add GOAMD64 architecture variants (https://github.com/golang/go/issues/25489)
