- using tcpip 1.2.1:
- i use my 386-40 heavily at work and it functions as an ftp server,
- a telnet server, and an nfs server with no noticable degradation
- in performance. (telnet is a little slow if the machine is real
- busy).

- i think you would need the programmers toolkit and source code to
- modify the program to do this filtering.

- i have seen no noticable performance increase when os/2 is run on a
- faster machine, but add more ram and the performance increase is
- incredible, my 8M 386-40 runs ok and about as quick as a 486-33 with
- 8M but put 16M in the 486 and it flies. the swap file is the
- bottleneck with os/2.

- i have to reboot about twice a month - but thats when i'm experimenting
- with the system, you also have to reboot when you change config.sys to
- have the changes take effect. if you change a tcpip data file then
- you may have to close and re-run the tcpip daemon that uses it.
