This may or may not be a problem with FreeBSD 6.x...have you installed a 
diagnostic tool like smartmon and run a disk check?  If the drive is in 
the process of failing, you might experience slowdowns like you've 
described.

Can you "dd if=/dev/da0 of=/dev/null bs=64k" [*] OK and at a reasonable 
speed?  Hit Cntl-T every minute or so...

[*]: or whatever device your SCSI drive appears at, if not da0.
