You seek a compromise: lower the MTU until your time loss problem goes
away, but not much lower as the overhead in packet reassembly becomes more
significant as MTU is lowered. I don't know what the actual minimum is,
but IIRC MTU < ~128 bytes doesn't usually achieve much. I'd start at the
MTU=512 Jeremy suggested.
