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.

Linux way way slower than Windows? (lemmy.ca)

So I jumped ship from Windows to Kubuntu last night, and It's mostly been pretty good. However my general performance of the computer has been abysmal. Like it takes upwards of 5 seconds to open anything. All of my hardware seems to be running at max speeds, so I have no idea why it would be so sluggish? It's as if I'm running on 2gb of ram and a cpu at like 1.5ghz. My specs are:

i7-8700k at 4.7ghz max Amd Rx 6750xt 16gb ram at 3200mhz Linux is on an m.2

Any ideas? This is practically unusable for any normal operations, let alone any gaming.

Update: So it seems like my CPU is being throttled to it's min of 800mhz because the temp is just below 100c. Not sure why it's so high because I never got that high even in intensive gaming on Windows

I've had similar problems in the past with an AIO, the pump should always be at 100%, so I usually do this through BIOS. My old Mobo had a dedicated pump pin, but the new one doesn't, so I put it on a fan one and configured it to 100% all times. If the pump is not at maximum it might not move enough water for the system to cool.

The problem here might be a difference between how Windows and Linux handle fan control, CHA_FAN1 is a chassis fan, it might be that Kubuntu is not using the CPU temp for it, instead relying on another sensor.

Although to be honest I don't think this might be causing your issue. I'm leaning more to thinking this is related to either the snaps or some problem with the disk you have Linux on. My recommendation is to test a live iso for different distros, if the live iso for Kubuntu works better than on the disk it might imply some issue with the disk, if it's also slow it might be a problem with Kubuntu, I would recommend then testing different distros with KDE Plasma, they would look and feel the same but might be faster if the problem is Ubuntu's snaps. I personally don't like it but I've heard people speak highly of Fedora and OpenSuse.
