That's probably just the advantage of having swap on a separate disk, but I've got both a "find /" and a "wc /usr/bin/*" running right now, and interactive performance is not noticeably degraded on 2.2.0-release with 64MB (and that is with two active users on the box right now). Concurrent filesystem and swap IO on the same spindle is always going to suck. --Stephen -- To unsubscribe, send a message with 'unsubscribe linux-mm my@address' in the body to majordomo@kvack.org.
