But their differentiation is that to improve performance they compile all the packages with newer instruction sets as the target as well as enabling more optimizations like LTO. And some are even optimized with PGO.
I find it odd to call a specific Linux distribution blazingly fast.
Gentoo with make.conf (/etc/portage/make.conf[1]) having "CFLAGS="-O3 -march=native -flto"" means that Gentoo, a Linux distribution, is performant?
[1] It is not a good idea to build everything with LTO or PGO enabled because not all packages support LTO / PGO cleanly. Do it on the basis of per-package.
I've seen claims of decent speed improvements when using CachyOS, though I can't say I've ever hunted down solid confirmation. I'm a bit wary of the project because I would have to put a lot of trust in them since they're rebuilding everything themselves and could easily introduce malware somewhere in there. (But I've been scared of distros before only to have it pointed out to me that some very well respected people are involved, so I could be worrying for nothing here too)
Does Gentoo have binpkgs with these compileflags? With CachyOS you don't have to compile, because it's a rolling binary distro. Regarding your [1]: They do that, systemd(or parts of it) are unoptimized, for instance. They don't apply that stuff blindly, only where it works.
For me it feels blazingly fast, even on obsolete KabyLake Core-I5/7(t) forcibly clocked down to about 800Mhz most of the times :)
It fucking flies without much effort. On modern systems even more so. While being rock solid. Without any crashes. Even under Plasma. When I'm reading about bugfixes regarding crashes under Plasma I just shrug and think "Waddya talkin about?". That may be hardware dependent, though, because they are old Lenovo Thinkcentres(1Litre SFF M910q tiny) with excellent firmware.
Using btrfs, profile-sync-demon, zram(Yes. Even with 32GB Ram!). Suspend/Resume working every single time. No glitches, hick-ups, ever. So far. Since 10th of June, 2024.
Edit: Almost always some music out of yt doodling in some bg-tab, in oh-so-slow FF, without any clicks, stuttering, or other breaks.
No need for yt-dlp, mpv at all. Except for dl/saving stuff, sometimes. While FF is rarely under 100 tabs.
Good for you. The 'oh-so-slow' regarding FF was meant as satirical btw. With what I'm using it for, it doesn't lag. Maybe because of https://github.com/graysky2/profile-sync-daemon mostly, and some other fine-tunings, which make it not touching the filesystem over and over again. I really recommend PSD. Not even insane amounts of RAM, it usually takes about 4 to 5GB, rarely going to 8, then shrinking back a while after closing too much tabs. Imagine that!1!! It's all about some sysctl settings :-)
Sideberry (Tree-Style-Tabs like extension) was the ugliest offender there. Though that may have been me misconfiguring it. OTOH I didn't manage to find settings where it didn't do that, and still looked like I wanted it to. At that time, maybe a year ago, I've thought of it as potential 'instant ssd-killer'. Couldn't be bothered. Deinstalled.
Now FF has some basic version of vertical tabs by Mozilla itself. It suffices(for now).
Thanks, PSD looks interesting. I only have 8 GB RAM at the moment, I will see if my motherboard supports more (it should support 16 GB at the very least). After the RAM upgrade, I will probably use PSD. Or is there a way to specify how many RAM it can use?
As for tabs, I like the way Vivaldi does it and allows me to customize.
