I'm running Solaris 2.4 using aspppd on my IPC. It's connecting my local
network to the internet via a 28.8 dial-up link. What's the recommended
MTU for such a connection? The reason I ask is that terminal IO is rather
'lumpy' and I've heard that a lower MTU will improve the responsiveness.
Since the default of 1500 is the same as ethernet I can't imagine it's
efficient. There are only a few machines on the local net and I have
verfied that the behavior is not because of other activity. No blinkin'
lights on the modem until I press keys and it's still sluggish.
Also, would a 4/300 make a better PPP server? The IPC does little more
than run sendmail, popper and aspppd. The modem only get's 21.6k
connections (it's rural) and I'm using the port at 38400 now. It would be
a simple matter to move the modem to the 4/300 if it would improve
throughput. The 4/300 is usually rather idle as well.
Thanks and email replies appreciated.
