In > fact, the swapon for files will also. ``swaping/paging'' imposes enough of a performance hit that my methodology already takes care of that, just don't swap more than you have memory, I rarely wait for my swap space usage to hit 50% before I toss more memory in a box. Of cource, the boarder cases already talked about are an exception to this condition (can't put enough physical RAM in most machines for them to be at 1 x RAM swapsize). -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation, Inc.
