You mailed me privately. Better replying to mailing list since this could be useful to others && please do not top quote. In data domenica 27 maggio 2018 15:27:13 CEST, hai scritto:
Please try different i/o schedulers and maybe ck or zen kernel for extra BFQ. But first try deadline scheduler. And, like I suggested, check if there's a difference in process and i/o priority between Ubuntu and Arch KDE.
How can I achieve this? I never changed the default scheduler before. I'd prefer to stay on the default kernel, because I don't have enough knowledge (and time or will) to maintain a custom kernel. The priority of the Baloo scheduler is the same between Debian and derivatives and Arch, as far as I can see.
Also, please consider filing an Arch bug with all relevant info. Since you tested this with the same kernel version on different distros, it's likely to be a configuration of the kernel and applications on each distro.
Sure I'll be doing that, but before I need to get more useful data to file a bug. -- fp
