Another timely Burton Group snapshot – see the full post for context-setting
So bearing all this in mind, I was interested to see a video on MSDN from Mark Russinovich which details the changes to the Windows 7 and Windows Server 2008R2 kernel (view it here if you are an OS geek like me.) In the video, Mark describes a number of significant changes in the kernel, such as the virtual elimination of spinlocks that control access to global kernel data structures (AKA global spinlocks.) The changes that Mark outlines are all designed to improve scalability of the Windows kernel in an increasingly multi-core and 64-bit world. It will be interesting to see how these changes improve Windows scalability in the future, and I wait for things like TPC benchmark numbers with bated breath.
