All I can say is "experiment with it".

It might be useful to renice kswapd so that userspace processes do not
increase its latency.


Hmm, increasing the min free kb to 64MB and renicing kswapd to -8 seems to solve the issue. However, for me it seems as not so good solution mainly because
2.6.6-bk4 kernel is just ok without any tweeks.




You're using 2.6.9, right? 2.6.10 should be better in this regard.
