Well, here's a current FreeBSD machine that has a couple 60GB raid boxes ccd'd together: Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/ccd0c 122255964 4 112475484 0% /mnt ds3.nas.nasa.gov > lmdd of=file bs=32k ^C600.25 MB in 27.46 seconds (21.8584 MB/sec) ds3.nas.nasa.gov > swapinfo Device 1024-blocks Used Avail Capacity Type /dev/wd0s1b 1023872 0 1023872 0% Interleaved Here's a NetBSD machine with a 155GB array: brunner > df -k . Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/sd7a 158057244 4 150154376 0% /mnt brunner > swapctl -l Device 1024-blocks Used Avail Capacity Priority /dev/sd0b 1099340 8 1099332 0% 0 brunner > lmdd of=file bs=32k ^C623.22 MB in 24.52 seconds (25.4209 MB/sec) Yes, substantial swap. I've probably fsck'd with smaller swap. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
