If I stick to 32bit will both cores be used, are there performance
benefits or just memory addressing etc of 64bit.

Thing is I want to use things like w32codecs and they do not seem to
be available for 64bit.

When I do top I was expecting to c a line for each CPU in the summary
section.  Is there a way of monitoring each CPU separately?
