We currently have some users (40) using a Terminal services application called Citrix. They connect to the home office on DSL or T1 lines through the internet could. We get frequent reports of latency in typing and opening files. This never happens on the LAN so I am guessing that is has to do with the internet connection. When I check the bandwidth we are using very little of our total. Some people suggest VPN, some Frame Relay, but I don't know much about Point to point T1 connection. What would you suggest to eliminate latency from our connection?? Who do you suggest as an ISP?? Articles on the web about dedcated point to point connections??

Go see Hugh at 4thefort.com....[aka Ft. Chaos] and ask this question in the forums hardware Q&A. He used to own an ISP service [sold it to a Cable Company]and probably can give you some leads to ISP's and also answer you LAN questions.

We have had a very large-scale deployment of Cirtix Metaframe at one of our high schools. From many weeks of testing, we have found that usually the internet connection and network is not to blame for latency. It is the server it's self. With a Dell Power Edge 2550 Dual PIII 1 Ghz with 2Gig ram. It could barley handle 15 users. The overall load was very low, but traffic was high, packet count wise.

When users are using the server, try and do some mirror the port on the switch and analyze it with a network analyzer. I'm sure you will find the Packets per second is extremely high.

The only way we where able to resolve the problem was with multiple servers and using load balancing. Adding an additional server, and using Citrix's load balancing capabilities; we where able to meet our requirement of 35-40 users.
