Not necessarily.  In a world with perfect TCP implementations, then yes.
Unfortunately, existing TCP implementations are not perfect and it is
often the case that two TCP connections, each requesting half the data,
can outperform one TCP connection requesting all the data.

This situation should change within a year as vendors switch to a better
TCP implementation (called FAST TCP).

Judging from the latency plots, the data losses are much better (i.e.,
much less).  I couldn't give you a quantitative evaluation, however.

Thank you.  There's still some work to be done.
