Anil- I'll try to take a stab at this...
For your network: Verify that you are not experiencing packet loss on the uplink from your Procurve switch to the Cisco Router. Make sure you have the speed and duplex setting hard-coded on each end. Aside from that, I would look into congestion management, as you may need to implement CBWFQ on the Router (assuming that the telnet sessions have lag, and are having to cross the T1 circuit. I seriously doubt this would be the issue on the Ethernet/FastEthernet interface. In fact, if Telnet is lagging from inside the network and the only device that has to be crossed is the switch, I'd check the connection between the Linux box and the switch, as well as the Subnet Mask/Default Gateway to ensure those are set correctly. For the friend's network: See "aside from that,..." comment above.

[7:70648] Our network is running a 3640 as a core router and several other smaller routers plus an HP Procurve for the Servers and LAN. We run BGP across two upstream networks. Now, for a long time we have had a slight lag on our network. For example, whenever I am logged into our Linux servers, I will be typing something and I will lose the cursor, then suddenly a bunch of letters will appear at the cursor. There are other examples. We have hunted up and down and not found a problem/solution. Now comes the interesting part. A friend of mine who has been running Linux for years used a Linux machine as a router for the last 3.5 years. At my urging he decided to try a Cisco because his server was getting old and needed an overhaul. Yesterday he did and now has the same problem. His config is very simple - he has a 2640 router running IOS 12.1 - one T-1 and one Ethernet port to which he has connected his Dialup equipment (he is a Dialup ISP). What gives? He is now bad mouthing Cisco even more than he did before! Any ideas appreciated.
