RE: slow queries over tcp/ip

[Chris Bipes <chris.bipes@xxxxxxxxxxxxxxx>]

We only use switches here, no hubs.  Our AS400 720 has two LAN cards running
100MB full duplex.  They are plugged into different switches.  I do not
think they have any special programming.  I need to check with our Network
Administrator who is not in yet.  Our router hold both physical IP address
as routes to the virtual IP address that is served via our internal DNS/WINS
servers.

If you are having performance problems I would use Ops Nav to monitor your
LAN interface and see how hard it is being hit.  Is your interface running
at 10/Half or 100/Half or 100/Full duplex?  100 full duplex should handle
400 PCs with ease.  I doubt that that is your bottle neck.  I would look at
your telnet servers and their run priority/time slice and the memory
available in the subsystem.  Two bits says that is where your performance in
dying.  We run the telnet server with a run pty of 15 and time slice of
2000.

Chris,

How did you define 2 connections to your switch?  We're running on an 830 @
4.5 latest cum with over 400 telnet users and we're constantly being
bombarded with folks getting knocked off with telnet errors and poor
response time.  I could really use another connection.  Thanks in advance.
