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.

Register-based calling convention for #golang functions is alive. Which is super great! Fingers crossed that it will land in Go 1.17 this ~August.

The Ryu algorithm for fast float64->decimal conversion.
Almost 5 years later it's merged, @dvyukov you should be happy, right? :D
Hope it will land in #golang 1.17 this August (or so) https://github.com/golang/go/issues/15672
Special thanks to @oudomphe CC: @ulfjack (Ryu author) and @calebspare

The results are looking phenomenal. On a set of application benchmarks we've been using, geomean improvement is 6%
