I've never seen an actively used box that had good performance when its working set was being bounced in and out of swap space. If a process has memory leaks, the leaked memory can happily go to swap and stay there with little impact, so long as you don't run into 32-bit address space issues. If you have multiple processes contending for a couple hundred IOPs of swap device performance, those processes will suffer. -- Mike Gerdts http://mgerdts.blogspot.com/ _______________________________________________ zones-discuss mailing list [email protected]
