Except that using softupdates for a ports checkout is faster than using async. IIRC, this is because directory creation on an async filesystem is still done synchronously. So 'async' isn't truely 'async'. Hence, I see a number of things, like extracting the ports tree, and doing buildworlds, to be faster on softupdates partitions than async. Of course, it'd be nice if it were otherwise, but... -- Matthew Fuller (MF4839) | fullermd@over-yonder.net Unix Systems Administrator | fullermd@linkfast.net Specializing in FreeBSD | http://www.over-yonder.net/ "The only reason I'm burning my candle at both ends, is because I haven't figured out how to light the middle yet" To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
