The Dolters(?) created a benchmark and saw small (though not _trivial_) improvements to both read and write latency without changing any code. It’s almost certainly worth trying if your apps would benefit from some marginal performance improvements in return for a little experimentation time. Zach Musgrave (DoltHub) [Getting the Best from Profile Guided Optimization](https://andrewwphillips.github.io/blog/pgo.html) — Related to the above item, PGO was a nifty addition to Go 1.21 (first previewed in 1.20) but there are some things worth appreciating if you want to get the most out of it.
