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 do have a AIO radiator. The pump itself is plugged into CHA_FAN1 and shows about 1600RPM, but I don't remember the normal speeds

Are your AIO fans, pump, etc. connected to the motherboard or through a USB hub?

I have some fans connected via hub, but the pump and aio fan are connexted directly to the motherboard

Do you know what model AiO you have? Some models report pump speeds as higher since they have multiple magnets triggering the RPM sensor, so the 1600 might actually be 800 or even 400, which is way too low for the pump.

I would try setting the pump (and AiO fan) to 100% speed in the Bios for testing. Some pumps work well with a fan curve, some don't.

Edit with more technical details: Normally each revolution should generate 2 Pulses on the rpm Feedback wire. But Pumps don't always follow this spec so might over or underreport their actual rpm.
