I am running 2.6.8-rc4 with Ingo's voluntary preempt patch O5, on Fedora 2. I'm using the default Gnome environment, reading mail with Evolution, browsing with Firefox, etc. I've 512MB of RAM.
At the same time, i'm processing some DVDs that i made - i'm extracting titles from a DVD to a dedicated hard-drive, saving audio and video tracks, etc with transcode-0.6.12 ( http://www.transcoding.org ). All that means reading/writing from/to large files on /dev/dvd and /dev/hde at high speeds.
The system is swapping excessively. There's no way the total size of the applications exceeds the size of RAM. There's plenty of room to spare, yet 16% of the 530MB of swap is used. The system's responsiveness as a desktop is very poor. If i touch an application, the drive thrashes raising it from the dead^H^H^H^H swap.
With the Fedora 2 kernel, this never happens. I did exactly the same things, and there was no excessive swapping. The system feels very responsive and fast.
I'll try to add Con Kolivas' hard swappiness patch to my customized kernel and see if that improves things.
In any case, the current behaviour is unacceptable.
