GCC 10 Enters Its Fourth Stage Of Development, 20 Bugs Of Highest Priority

[pal666]

By the way, if someone could point to a how-to to get LTO working with the kernel would be appreciated. I tried Andi Kleen's patches before but couldn't make it work... ... also there might be better tweaks I haven't talked about here, feel free to share them.

your fps are not spent in kernel, so optimizing kernel is not going to help. you should try optimizing mesa and game itself. and nothing will help if game is gpu-bound

it looks like the only major c++20 feature missing the boat is modules

Well, I haven't pinpointed if the different settings or the compilation flags were responsible, but a gain from 27 FPS to 36 FPS to my Kernel customizations is what I have observed in my own testing - good enough for me to be noticeable. And that particular game of the DX9 era is CPU bound by nature - the miserable overall performance for the tested hardware (R5 2600 / Vega 56) must come from a regression somewhere in the stack and already reported the issue. I've also customized Mesa but it turned out to be already at its limits, at least I couldn't gain anything with my custom compilation flags there. That was rather disappointing to see, but at least the out-of-the-box experience is quite decent already.

do you realize that if "faster compiler" did 33% speed increase, your game has to be spending more than 100% of its time in kernel?
