James and anyone else who can help,

Further to the details regarding poor performance of Telnet. We are looking
at converting out current DTC users (possibly upto 800 users) to Telnet.
Could anyone confirm if there are any performance problems with Telnet, or
if Telnet is not a problem. We are running on 2 different hardware
platforms, all running the same software level.

2 x HP979/400, 1 X HP989/650.

The 800 users will be split across the systems, with the majority on the
HP989/650, and one of the HP979/400's.

Both have sufficient memory and disc space.

I would be grateful of any responses.

Thanking everyone in advance.
