I recently started a new job where our team evaluates commercial laptops. I've just learned that performance scores from our image were consistently higher than on factory loads for dual core machines.
I found this rather odd since our baseline load seems very bloated and far from optimized. Then I discovered something interesting. Someone did not properly sysprep the machine our baseline image was taken from and as a result the ACPI Uniprocessor PC HAL was being installed instead of the ACPI Multiprocessor PC HAL. (For clarification - the multi is also used on the factory load.) I have since fixed this issue.
Benchmarking the Uniprocessor HAL against the Multiprocessor HAL on identical machines with identical loads I found an unexpected surprise. The uniprocessor HAL creamed the multiprocessor HAL by almost 200 points. Any thoughts?
