Got it, we'll look to PGO/LGO if we go down this path, thanks!

FYI - SERVER-72505. Just deleted moutline-atomics because it is implied by march=armv8.2-a. We also don't do much (if any) cross compiling. Any distro we release for we compile on. I would very much temper expectations on getting some perf improvements out of this ticket.

 

We also have a list of experimental optimizations we tried out and didn't see much improvement from them (those were more for x86 though).

 

If you are looking for perf wins I think PGO/LTO might get some large perf wins.
