P1020421 Before and After Microsofts Bulldozer Scheduler Patches: AMD Opteron Interlagos 6274 Server

Last week during the CES period, Microsoft finally released a set of Windows 7/2008 R2 operating system patches (KB2646060 and KB2645594) to change core parking and scheduler behaviour to more effectively utilize the "Bulldozer" modules (first dreamt of in 2006) found in newer AMD FX desktop and Opteron server chips. Using a 2P Opteron 'Interlagos' 6274 which is 115W TDP part and has a nominal frequency of 2.2GHz with all cores loaded, we do a quick check for any performance improvements.
