First question. Did you try the experiment:
cat >/dev/null <100byte.in ?
Second question. Why do you think that the cat command is comparable to
inserting a structured object into a sophisticated queue system that ensures
reliability performance at high numbers?
If this is a rhetorical question, then what is your expectation of the cost
of queuing a mail message and on what basis did you make that expectation?
Mark.
