I'm not actually seeing this myself. I just don't see any accumulating slowdown. I see sometime dramatic slowdown, probably after USB mass copy, may be related to the cache problem discussed recently, but this do not stay after the next reboot.

I see this too, after just a little swappage, as well as doing copies to/from USB devices and working with large media files.

The more swappage that occurs, the slower it gets. Very shortly I have to reboot but that always ends with a kernel panic.

Can the cache be swapped out/in now? IIRC, it wasn't allowed before.

just for testing, you could try dropping your cache once in a while.

Thanks! I'll try that out. I had completely forgotten the kernel docs. I had written them off a long time ago because when I needed them they had been incorrect, too vague or contradictory. I'll fetch a current copy. jd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
