No, you should definitely follow the same basic methodology under Linux that you would under any other OS. If you've got less than about 256 MBs of memory, swap should be doulbe the size of your memory. If you've got more than that, it should be the size of your memory. If you've got some reason to deviate from that rule, you'll know you have a good reason. If you're in doubt, you probably don't have a good reason. (Btw, the reason you should really have a swap *partition* at least the size of your physical memory is that that's where the crash dump gets written when your kernel panics. You want that so you can figure out why it panic'ed. After you reboot, it should end up in /var/crash or thereabouts. Note that this is generic Unix stuff... I don't know that Linux does things exactly that way.) -- gabriel rosenkoetter gr@eclipsed.net Attachment:
