i'm not aware of benchmarks

The major improvements comes from a better management of the memory(-ies), or a better handling of the OpenGL extensions, etc... these kind of stuff aren't very CPU intensive, it just needs to be well thought. One thing that can be CPU intensive is the shaders compilation, but I think it's done with LLVM, not Mesa.

Every time I get my set up just right, along comes an update that blows everything to pieces. The last straw for me was Nextcloud on Apache. I had gotten it up and running, everything was syncing nicely both locally and Internettingly and then along comes an update and it all falls to pieces and it never came back on line properly. It was like it took brain damage. The time I spent resolving the issue was unacceptable. I do Nextcloud on other installs and they run swimingly, no worries, Ace! If the chappy is having issues with Ubuntu, a distro based on release cycles, then what chance does he have with Arch, a fast moving system? All he need do is find out his problem and, theoretically, have it fixed. With Arch, he could find the problem and then along comes another issue next update. It's nonsense to use it when you need to get shit done, and can't risk the downtime without thorough testing. And that wouldmean wasted time and resources anyway (or simply a ual-boot).
I am well aware of pinning versions, but after a while, what's the bloody point of running a rolling distro if you're pinning everything.
Plus, he might also simply just like/prefer Ubuntu.Hi

Using the newest binaries from PPAs is a lot faster and more convenient than compiling everything from AUR. Just don't use an ancient Ubuntu, and it'll be fine.

I don't think compiler optimizations are doing a lot for mesa right now. Even with -O0 -ggdb3, real games are only somewhat slower. I think that even small improvements in how mesa handles OpenGL will have most likely a bigger impact, so I believe starting to look into the hardcore compiler optimizations will make sense, once mesa is really well optimized through and through.
That said, I have tried Ofast and LTO and I did not notice major differences in games. I did notice major differences in compile time though. LTO easily triples the time it takes to build mesa for (currently) very little benefit.
