I never actually said boot time is affected whether the page file is enabled or not. Just tossed it out there that regardless to me it seemed about the same. I can only speculate Vista takes less time to fire up because 2 cores vs 4 means less os overhead.How can boot time be affected by the page file? The page file only gets initialized in the late stages of the boot process. And none of the pages in memory are "old enough" or "access infrequently enough" at that point in time for them to be paged out unless memory is low. But booting Windows doesn't take 4GB so that still doesn't explain where these 10 seconds of quicker boot time are coming from...
