|The project I am working on uses Matrox Extio F2408 KVM extenders to drive 12 HD monitors from one computer. The time it takes to draw the custom background image (1920x1080) is 500 times slower under Windows Server 2008 R2 versus Windows 7 or XP. Matrox says that Server 2008 is the wrong OS for doing high performance video, but has failed to explain exactly what is so slow about a server OS versus a desktop OS.|
Note that we did swap video cards and put an nVidia card in the server. Same slow performance as the Matrox card.
Then, at the suggestion from Matrox, we installed/enabled the Windows Desktop Experience, and the Aero theme. So the desktop looked like Win7 with the fancy graphical effects and stuff. No change in performance of my application.
So, could someone please explain why a server OS is so much slower than desktop OS in general. Also if anyone has tuning tips for improving video performance under Server 2008 R2 I would appreciate it.
