There is something very wrong here. Cat'ing two blocks of data should
take milliseconds. Are you out of memory (does vmstat show paging?)?
When your cat is << .1 seconds or so then rerun your tests. Wait a
minute, did you run the cat WHILE you were trying to do the deliveries?
If so, then that is about right as qmail is beating on your hard disk.
Your qmail-inject seem like they are off by about a factor of 10 or less
(since qmail-send isn't running), but that is just a swag (assuming
about a hundred other things like a properly configured file system, no
swapping/page stealing (sufficent memory), and a current-technology SCSI
non-IDE drive).
