Do you mean paging in general or thrashing? I always thought: paging good, thrashing bad. A good effecient paging system, always moving data between memory and disk, is great. It's when you have the greater than physical memory working set that things go to hell in a hand basket. Did Linux ever do the old trick of "We've too much going on! You! (randomly points to a process) take a seat! You're not running for a while!" and the process gets totatlly swapped out for a "while," not even scheduled? mrc -- Mike Castle Life is like a clock: You can work constantly dalgoda@ix.netcom.com and be right all the time, or not work at all www.netcom.com/~dalgoda/ and be right at least twice a day. -- mrc We are all of us living in the shadow of Manhattan. -- Watchmen
