It really made a difference back in Windows NT 3.51 and 4.0.

We used it to keep a Apache threads per core on our servers back in those days.

The scheduler wasn't still optimized for the .com loads and the Apache threads kept jumping between cores.

Also Apache still wasn't that optimized for Windows as well.
