We have been trialling terminal services for a few months and are realizing that we have a severe limitation in that when users are browsing the internet, the images on web pages are much slower to draw on the screen than if they were operating from the local PC directly to the internet. Much worse though, is that when they scroll their screen the images have to be drawn every single time.
I understand that this is because the display is being sent every time directly from the server rather than the image file being cached locally. I have scoured the internet trying a number of registry, IE and RDP changes to try to speed this up, such as 'Eliminate IE Flickering', Force off-screen compositing even under terminal server also changing the hardware acceleration value of the graphics driver on both server and client. I even tried changing MTU value and terminal to 2008 server (improved RDP supposedly). Is there anything else that i might not be thinking of or is this just they way it is. This is an important issue as it will affect the outcome of whether me roll out term svcs or not.
