thx guys for your post.
The book I am refering is manning's '.net multithreading'
and the .NET do provide a way to specify thread to a
target CPU. It's through ProcessThread.IdealProcessor
Property.
Anyway, I think I can draw the following conclusion of
this question:
system will manage threads created by .NET program and
only reason to improve the performance by mannually set
thread to be running on a specific CPU is because of the
improvement of CPU cache hit.
Am I right
