I currently have a RAID-1 rebuild running and cat /proc/mdstat shows
speed=1481K/sec. This seems incredibly slow to me. That's just just
about one and a half megs per second. I'm wondering if this machine
has some more serious hardware problem. No errors showing up in dmesg
or /var/log/messages or anything though.
