Hmm...I'd have to disagree. Are you perhaps assuming a certain threshold
(>100mbps, for instance)?
I use rate limiting for some of my customers, and when correctly
configured (you _must_ use the right burst sizes), you will get the
exact rate specified, TCP or not. However, I've never had to rate-limit
above 30mbps, so perhaps you have some experience that I don't.
