Klunky keyboard echoing in Terminal Services Sessions
Posted on 2007-03-20
Good Morning (at least for me) Experts,
I have approx 250 users that login to 4 TS boxes. Two are TS and nothing else two are TS + DNS + AD, probably not the best scenario but we do with what we have.
The boxes are for the most part identical Dual Xeon 3.0 with 6 GB RAM and a pair of Raptor drives in a mirror configuration.
On average we have 60 users / box with each user having at least 25 MB of our apps in RAM + what ever windows uses for each session (from some MS docs I would class these users as knowledge workers so that should be about 10 MB of RAM, can anyone confirm or deny this is close?).
I have one group of customers saying that when they type larger sections of text (product descriptions and things with more than 1 or two words like names, etc) the echo response from when they type to when the text on the screen appears can have 2+ second delays. It seems this is making it difficult to navigate as you have to keep going back to make sure the text has all appeared before moving on.
Most users are coming from behind a firewall of their own and this particualar group claim they can attach to other TS servers in other buildings and not experience this delay. I have not really been able to experience the lengthy delays they claim to be getting. I see little blips now and again (open notepad and hold a key down and watch the text scroll) but they claim it actually appear chunky in this same basic test).
I have a firewall with forwards 3389 to a 2x load balancer with 4 servers, it then send ths data off to the TS box.
Anyone have any suggestions? How can I tell if I am in a RAM shortage causing excess swapping? My % usage of page file is no more than 10-15%, of 6G if RAM Memory/Available RAM is 4271MB with 40 users on now and CPU utilization rarely goes above 40. If you need more please let me know. These folks are driving me nuts cause I can't reproduce the issue and have not been able to find anything that would point me in any direction.
Begging may not be becoming or required but I am begging please someone poke a small hole in my blinders so I may see which direction to head or at least not to head.
