[WBEL-users] Virtual memory tuning?

[Christian Nygaard]

Hi I'm running a couple of WBEL boxes with many users on them which in 
turn is running out of memory thus swapping much. Now the impact is that 
the system only freezes for moments when its swapping out pages to disk, 
then everything is running fine again. Does anyone know how to tune the 
kernel so it swaps more constantly/swaps out less pages, so the freeze 
effect is not so apparent? It runs smooth for long amounts of time, then
freezes for 10-15 seconds, then runs smooth again and so forth.

I've tried to fiddle on vm.bdflush and vm.pagecache

Thankful for any good /proc/sys/vm hints :)
