In a post by Helge Klein at IT from inside he has done sometesting regarding the impact of utilising ClearType across RDP connections and the upshot of it is that this has the potential to increase your bandwidth usage by 300% or if using 32bit colour this can be as high as 600%. Your mileage may vary- best to test extensively before you turn this on?

This is based on server 2008 CTP, June 2007 so this may improve before the official release?

colour - for my US readers this is how it is spelt in all other English speaking countries other than the US ;-))

ClearType Bandwidth Revisited - Testing 32 Bit Color Depth

In an earlier post I wrote about how bandwidth requirements of the RDP protocol are affected by enabling font smoothing (ClearType over RDP version 6) on Windows Server 2008.

Jan, a reader of that article, posted an interesting comment: he had heard that RDP version 6 was optimized for a color depth of 32 bits and asked me to repeat my tests with that setting, which leads to an interesting question: how is font smoothing bandwidth usage affected by the color depth used?

When I prepared the test environment for my initial article on this subject I consciously chose a color depth of 16 bits, mainly because I thought that 16 bits is the most widely used color depth on production systems. I did not, however, think about how different color depths might change the numbers measured.

more details at source...
