Re^2: How much computational speed boost occurs for CALL64 and multi processors??

Dear Alex,
How do I check for core parking feature in Win 7? Yes I am running two programs, one in dual core and another in i3. Core i3 I am using 4 cores. On dual core, Win xp and on i3 Win 7 is installed.

Regards,
