Agreed, sleeping processes and such like. That's why the idle state of 140MB swapped out doesn't bother me. > and using some (in this case 800M) of cache can speed things up more then > swapping out useless data slow's it down. The trouble is that, in this case, the system is thrashing swap and slowing down to a crawl. I would have thought that not thrashing swap would speed things up more than keeping a file cache. It's doing work which is completly internal (no disk IO until it's finished calculations), but needs lots of memory. > So don't worry... it's normal behaviour...

It might be normal, but it's crucifying performance in this case. Cheers Paul -- Paul Sargent mailto: [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
