Windows 2000 server Standard and dual core processors 1

[itbloke99]

Hi Everyone,

With the advent of the new Xeon dual core processors (each of which core is hyperthreading, I believe), there is the potential for W2K to 'see' 8 processors in a dual CPU server.

My question is: Will W2K Server Standard edition support this?

Many thanks for any replies.

For Windows NT and Windows 2000, the answer is "It doesn't even know." These operating systems are not hyperthreading-aware because they were written before hyperthreading was invented. If you enable hyperthreading, then each of your CPUs looks like two separate CPUs to these operating systems. (And will get charged as two separate CPUs for licensing purposes.) Since the scheduler doesn't realize the connection between the virtual CPUs, it can end up doing a worse job than if you had never enabled hyperthreading to begin with.
