Dispatcher lock

Hi

http://www.osronline.com/article.cfm?id=93
In that article “dispatcher lock” is used as a “kernel dispatcher object” that can be waited.

But in that interview, if I am not wrong, it is used as a spin lock.

Can someone please clarify what “dispatcher lock” stands for? Also Microsoft said farewell to what?

Thanks…

The lock (a spin lock) used to guard the state of all dispatcher objects before win7. This lock was a bottleneck. In win7 this lock was completely removed (farewell!) and dispatch object relative locks were used instead, eliminating this particular bottleneck
