    The OS shouldn't even be a difference then, perhaps 7z is performing memory allocation inside the hot path (since that differs between OS:es) or it's the change in compilers as danger suggested.

    Arch was, but Plasma and Vivaldi (on every DE) weren't. Sorry, should've clarified that.

    The reason for the improved feeling is down to the higher kernel ticks of Clear's kernel vs. Arch's: 1000 Hz against 300 Hz.

    Now, if you were to use Canonical's "lowlatency" kernel (1000 Hz + PREEMPT) and combine that with some basic tweaks [performance governor & kyber IO-scheduler & swappiness=1 & nowatchdog & irqbalance & triple-buffering & some more I can't remember right now] your mind probably wouldn't even be able to handle all the awesomness!

    Perhaps 7z for Windows was compiled with a different compiler (MSVC?) and optimization flags what turn out better performance in this particular case?

    These benchmarks amaze me sometimes. Few last times it has lost and now it won even against Clear. I wonder if it's not related to power governor and this laptop? Or mitigations perhaps.

(Ubuntu, sure, but not Clear). I mean, it's nothing BUT CPU and RAM, so the only thing I can come up with is an issue in the scheduler or something like that. Anyone have any better ideas?

    In those benchmarks where it makes sense it would be great to post not just absolute numbers, but a percentage distance from each best achiever. Likewise it may be interesting then to have a sum / avg of all those distances per tested config and see the ranking that way.
