I'm not Jordan, anyway, it (naturally) has the best effect in situations when you're going to rm -rf something, or to extract tarballs with zillions of small files or symlinks. As for Jordan, remember that he's ``Mr. Sys Install'' in FreeBSD, thus i believe this situation arises more often to him than to the average user. Also remember the `-u' flag to mount (``update mount''). You can easily do: mount -u -o async /usr rm -rf /usr/obj mount -u -o noasync /usr ...if you wanna accelerate some particular i-node intensive operation, without risking too much as the default state. I'm using this method quite often. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
