Plasma freezes during high disk activity (solved) in c/[email protected]

Thank you all for your ideas, I managed to solve the problem. It was somewhat hardware related, but not really.

I was using BTRFS, which creates a lot of write amplification and aged SSDs don't handle that well. According to a study from 2017, btrfs can cause up to 32x write amplification, absolutely hammering its performance: https://ar5iv.labs.arxiv.org/html/1707.08514

I converted my system to RAID0 using EXT4 and the stutters and freezes are gone.

I have a few dodgy cheap SSDs, so I'm not surprised by slow I/O performance in general. But my Plasma desktop frequently freezes for 1-3 seconds (including the cursor!) whenever there is high IO load, for example while installing a Steam game.

Updating the screen should be completely independent from I/O, shouldn't it? Is there anything I could've misconfigured in my Arch Linux? I'm running Plasma 6.1.4 in Wayland.

Try searching it on https://btdig.com/, a DHT search engine. Most of the torrents there are very old and have barely any seeds. Be patient. The last thing I downloaded from there took 1-2 weeks to complete.

Seed everything, but seed bad media more in c/[email protected]

That's what I do. I seed for as long as it remains on disk.
