From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I swear it is my machine or something, but despite CachyOS claiming being faster and more optimized I have yet to benchmark it as faster than the stock kernel for things I play around with. I wrote an application in rust to process a large text file and it both compiled and ran slower on CachyOS. I play around with llama.cpp and again it compiles and runs slower on CachyOS. I want to like Cachy, but right now all I can see is a bunch of window dressing to stock Arch with KDE and a couple of themes that I would rather change to default.
Also, why in the hell am I being asked to make a wifi password encryption key with the damn USB installer? CachyOS is not the only one. A lot of KDE using distros pop up the encryption window when you setup WiFi on the install image. Why? You want me to temporarily encrypt my wifi password on a temporary live image??? I just slows me down.
Anyways, I'm sure I'm crazy and clearly it is fast for somebody, but I can't even get games to benchmark higher.
Cachy is a great live usb because it has zfs.
Did you test with different kernels? Them using a custom scheduler that prioritizes desktop applications might cause background things to run slower.
Plus, the use of ananicy (cpu/ram limiter) limits stuff like that as well.
I use cachyos because they set up zram, anf uksmd by defualt. That's ram compression and deduplication, and it'a pretty powerful in my experience. If you're using cachyos, then
uksmdstatsandzramctlcan give you an idea of how much you are saving.I used the default v3 kernel that Cachy installs by default. My guess is the workloads I have are Ram I/O bound and that just doesn't mesh with the scheduler. I'm literally rooting for it to be faster because I want caring about scheduler and optimization to matter, but freaking stock Linux Mint ran the loads faster.
