I just had an interesting thought... Has anyone done an analysis of how having a smaller MTU affects slow-start? It seems to me that a TCP session would come up to speed about 3 times faster with a mtu of ~500 vs a mtu of ~1500. BTW, I can confirm that a MTU of ~500 does seem to make problems related to Flow control problems and noisy line conditions almost go away. We tend to not tell our users about the smaller mtu setting, though, but instead help them to fix their CTS/RTS or line problem. - Forrest W.
