Look at the temperature when you are pushing the IO really hard. Some devices will throttle when hot.
Is this on a laptop? Do you have any indoor pets that have fur? Yaks shed a lot this time of year.
- everdrive 4mo agoI'll check that out. In my case I had moved straight from Fedora and was using LUKS + EXT4 -- with no issues whatsoever. Further, rather than losing some write speed, my system will actually hang quite aggressively. It seems to be CPU-related, but perhaps it's disk reads that are hanging? (or maybe both) My PC case is also not extra-hairy :)
- Bender 4mo agoTo benchmark the encryption if you suspect CPU related, try cryptsetup benchmark though it's more useful if it was run prior on your previous OS installation. For storage, fio [1] may be useful but that is a much more involved topic and having baseline tests run in your former OS that you said worked fine.
