Subject: Re: Multiple Processors on Windows 64-bit

Well, I'm not sure the 'start /affinity' approach is fixing my problem
either... the applications still seem to trade off computing time.
This might be for a couple of reasons:

1) Does Ruby try to be *smart* and consolidate all Ruby processes in one thread?
2) My Ruby applications are starting up and making calls to a Windows
application via an OLE interface, so maybe the referenced Windows
applications are running on the same processor.

Suggestions?
