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