Try turning off TCP extensions by entering these two commands (as
root):
sysctl -w net.inet.tcp.rfc1323=0
sysctl -w net.inet.tcp.rfc1644=0
then see if the telnet's any snappier. If it does help, then edit
/etc/sysconfig. Look for the line
tcp_extensions=YES
and change the YES to NO.

I scrambled to the top of the precipice where Nick was waiting. "That
was fun," I said. "You bet it was," said Nick. "Let's climb higher."
"No," I said. "I think we should be heading back now." "We have time,"
Nick insisted. I said we didn't, and Nick said we did. We argued back
and forth like that for about 20 minutes, then finally decided to head
back. I didn't say it was an interesting story. -- Jack Handey
