Visio 2003 sluggish on Win2K Terminal Server
Visio 2003 seems more sluggish on repaints in a terminal session than
previous versions. Running ica (Citrix) and turning speed screen on helped some, but still pretty bad. Plenty of RAM processors, etc. suspect repaint/display issue. Any tips for optimizing Visio 2003 in terminal environment (rdp or ica based) much appreciated. |

Visio 2003 sluggish on Win2K Terminal Server
With Citrix/ICA the application runs on the server. Typical bottlenecks are
Not enough memory allocated to the user application (visio takes a lot, and with large drawings can overwhelm even a small standalone system) Thin-client applications work best when the server and client are local to each other, WAN performance has always been a problem with applications that are screen and keyboard/mouse intensive. In a WAN environment speed RARELY is the issue, it is network latency (i.e. time to redesign the solution) Too many users on the server (takes cycles) Al "RichAtShepherd" wrote in message news Visio 2003 seems more sluggish on repaints in a terminal session than previous versions.

Visio 2003 sluggish on Win2K Terminal Server
Thanks Al.. I should have specified, I am running in a high bandwith LAN
environment. Also have a multiprocessor server wth many GBs RAM and perf mon shows memory/processor utilization not an issue. Also, issue same for small or new drawings.

Visio 2003 sluggish on Win2K Terminal Server
Tytpically, when we heard "repaint/display" issues we start to look for
network latency problems, which are not the same as bandwidth. User sat with thin-client requires that we have network delay on the average of less than 50ms. You might try a simple ping test from the client workstation to see what yours is. I worked with one client where we found over a second delay in his gigabit core because of routing problems.

Visio 2003 sluggish on Win2K Terminal Server
Thanks again Al. I see your point about taking latency from granted on a LAN
so I did ping our terminal servers and got 1ms for all pings. I take it that you have seen Visio 2003 work reasonably well in a terminal environment? I guess that is my question - can it work comparably well to a local for the average flow chart sized (pretty small) drawing? or is it, like CAD, something you just have to run on a PC?

Visio 2003 sluggish on Win2K Terminal Server
Typically what we have to do is to take traces with tools such as NAI
Sniffer to profile the application and see where the delay in the screen write is. You have to remember that these apps (citrix etc.) were originally developed for support of text based applications and remote desktop support. I don't know what you're trying to do with Visio, but, IMHO user sat with thin-client is usually inversely proportional to the amount of screen activity that has to go across the network. It will never be as good as locally implemented (assuming the local device is configured appropriately). Al ps It all goes across the network "RichAtShepherd" wrote in message news Thanks again Al.
