i think you have two things confused.  raising the mtu will "speed up
the modem" since you get more data for less overhead, however
*lowering* the mtu will increase interactivity, since each packet is
smaller, the transmit time is shorter, so the next one can get in/out
sooner.  you stand a better chance of getting a "word" in edgewise if
the other guy is using smaller "phrases".
