Off-topic to most of the points the article is making, but I'm happy to finally have some mathematical basis to my observation that saturating IO on a Linux system slows it down exponentially (or at least very non-linearly).
- janci 5y agoThis makes me want o throw the computer out of the window. Copying a large file between two partitions on the same SSD makes the computer absolutely unusable - mouse freezing, sound freezing
- dvdkon 5y agoI've found that setting resource limits via cgroups for the whole session makes the slowdowns much more manageable. It's definitely not ideal, I'd prefer some more elaborate system where each launched app was able to use only up to 90% of system resources, with some 5% always reserved for things like Xorg, the WM and such (and that's doable, I just didn't bother), but it does work.
