	I wonder if this is in any way related to the extremely slow
performance we get with Telnet.  We run NCSA Telnet 2.4 and 2.5 on
Mac-IIci's running 7.0.1 w/ MaTCP 1.1 or 1.1.1 on a relatively lightly
loaded thin ether segment.  Telnetting to an otherwise idle Ultrix box
sitting right next to my Mac, I get performance (for big blocks of text,
full screen updates in a 40-line window) that seems to me to be about on a
par with a 9600 bps connection.  Currently, I'm at home running kermit (also
with a 40-line screen size) over a 19.2 V.32bis connection to a terminal
server telnetting to that same Ultrix box through GOK how many bridges,
repeaters, etc and getting performance which is about as good.
