As I mentioned earlier, if you have Comcast, you have SpeedBoost. If
you have SpeedBoost, your transfer rate cap changes over the course of
the transfer.  A 1MB file will have a different average transfer rate
from a 1GB file, because that 1GB file will see a throughput drop
somewhere early into the file.  What you *really* want to do is
measure your throughput along 10s intervals over the course of a 2min
transfer.  You should be able to find where SpeedBoost drops out
there.
