- I already have SLIP running. But the troughput on 9600 baud is a

- CSLIP won't improve your throughput much as compared with SLIP, but it
- will help a lot with interactive responsiveness.
-
- CSLIP uses the clever techniques described in RFC-1144 to reduce the
- size of the TCP header, and its contribution to the protocol overhead
- cost of each packet that must traverse the link. The TCP header
- comprises a very large fraction of a typical single-data-character
- interactive telnet packet, but it's a relatively smaller part of a
- typical large FTP packet.
-
- So the effect on throughput won't be as dramatic as the effect on
- perceived interactive latency. If you're hoping for a big throughput
- jump, you may be disappointed with the degree of improvement that
- results from all the work you're expending.
