cmd/compile: add reassociate pass to rebalance commutative operations.
That's one small SSA pass for compiler, one giant leap for #golang performance 😉

cmd/compile: add reassociate pass to rebalance commutative operations by ryan-berger · Pull Request #60015 · golang/go
Currently the compiler groups expressions with commutative operations such as a + b + c + d as so: (a + (b + (c + d))) which is suboptimal for CPU instruction pipelining.

> Thanks to work in Go 1.21 cycle, the execution tracer’s run-time overhead was reduced from about -10% throughput and +10% request latency in web services to about 1% in both for most applications.

“Go 1.21 Release Candidate” by @elibendersky — go.dev/blog/go1.21rc
> Go 1.21 improves build speed by up to 6%, largely thanks to building the compiler itself with PGO.

> SwissTable: Google3 may want to do some benchmarking on this. Maps are used heavily in google3. This may be of value to us.
There is a chance that next #golang releases will have a faster map implementation!

Felix Geisendörfer:
Interesting proposal from Russ Cox to improve the accuracy of the mutex profiler in #golang.
If you hold a mutex for 10ms and 5 goroutines wait for 10ms each, only 10ms of contention are recorded. The proposal is to change this to 50ms 👍🏻

Analyzing Go Build Times
Go is often praised for its fast build times.
While they are pretty quick, they are slow enough that I spend a lot of time waiting for them, enough that it prompted me to go down the rabbit hole of thoroughly analyzing them.
