Pardon me if this seems like a snarky question... But if there's a 'measurable' increase in performance, why didn't Tom's measure anything???? (except footprint)
Bone to pick: Page 1, Paragraph 4:
Thanks to a technique called memory remapping, it is possible to move around parts of the system memory in such a way that the full 4 GB is still available for use. The trouble is that this feature had to be deactivated in Windows Vista due to compatibility issues.
The above statement is incorrect. This is a 32 bit Windows issue, and affects ALL consumer versions of the OS. Not just Vista 32. PAE mode was/is enabled only for security reasons (DEP) in XP SP2, and not as a means to use more RAM. The reason why remains the same: Using PAE extensions requires drivers that are 64 bit address~aware. If not, any time a driver or app attempts a Direct Memory Access call to an address which the OS mapped elsewhere under PAE, errors get thrown, screens turn blue, and people send (even more) hate mail to Microsoft. And if it's the case that drivers and apps have to be 64 bit address aware, then you may as well just go to a 64 bit OS in the first place...
Thanks for the command to deactivate Hibernation, though. (powercfg -H off) - the Author is right on this one: With 4GB of RAM, I've found it faster just to start Windows normally.
