Can you please list which kernel you were using for the server/workstation benchmarks for openSUSE 11.2?
There are two flavors,
-desktop (which is optimized and configured for desktop use)
-default (which optimized and configured for workstation/server use)
By default openSUSE 11.2 will install the desktop kernel so unless it was changed from the default install you would have had the 2.6.31-desktop kernel installed when running your tests.
