IPFW Bandwidth throttling?

[Chris McGee]

I am trying to limit outgoing SMTP traffic to about 14 Mbps and these are
the IPFW rules I am using.

	${fwcmd} add pipe 1 tcp from 192.168.0.0/24 to any 25 out via dc0
        ${fwcmd} pipe 1 config bw 14Mbit/s

I've tried multiple tweaks to the pipe rule and I seem to be missing
something.  I only get about half the bandwidth I specify.  Is this normal
behavior?  Is there something wrong with the rule I'm running?

Thanks,
Chris
