Just for curiosity, did you tried my latest
ftp://e-mind.com/pub/linux/arca-tree/2.2.0-pre9_arca-2.gz ?

I would like if you would apply it, recompile and reboot and see how it
feels. You should not waste more than 5/10 minutes to do that.

kswapd is not an issue. kswapd has nothing to do with performances. Feel
free to change kswapd rating as you want to see with your eyes.

The _problem_ of pre9 is try_to_free_pages(). I just posted a patch that I
think could help (note never tried such patch myself though).
