I have talked to people using various gateways
from mainframes to PC Lans, and none of them
ever seem to be totally satisfied.  I hear that
Attachmates become erratic with high loads, and
that Mitek is too expensive.

The IBM TCP/IP offerings look great in theory,
I should be able to use TCP/IP as my LAN and do
all PC terminal sessions with a 3270 version of
Telnet and all file transfers with FTP.  BUT

BUT---I hear that the performance of IBM's TCP/IP
is not soo good.  The 3172 connection from the LAN
to the Mainframe doesn't do much work and so the
Mainframe chews cycles managing IP packets.

I have heard that the maximum throughput is 600Kbps.

Is anyone using TPC/IP as an alternative to a
typical PC gateway, and how do you like it?  How
is the performance working out for you?  What has
anyone else heard about the future performance
of the TCP/IP products?

I *will* post a summary if I get interesting
responses.
