Bill - No screw-up there, that's indeed what typically happens.

Soo-hyeong & Polly,

If you take the conversation off-line, please share with the list any
that you come to. I, for one, would be very interested.

My limited experience with heavy-tailed distributions has always been less
satisfactory. I think that because the probability that very long file sizes
be drawn is so low (though non-negligible), the sample average file size is
always less than the true average of the distribution. The result I get is
the simulated offered traffic is less than the expected offered traffic,
ironically, performance ends up looking better than expected rather than

Or it could be that I screwed something up. :-)
