I don't know how exactly it works under Windows, but at least under Linux such optimizations usually don't pay off much since most used pages are already kept in the RAM anyway.
My HDD on Linux barely has any disk access and is perfectly usable, meanwhile windows just loves trashing it for minutes, even with page file & unneeded services disabled.

RAM cached profile, dns proxy, makes for really smoother browsing on older machines.
