Well, there is a problem with that strategy: not only are individual processes limited to 2 GB, but all your (user space) programs together are as well! And while the kernel can use some more, it only uses 64 MB at most in any case.'
So, the only thing that could benefit would be disk cache. It would be really silly to swap that. And if you don't use a page file, it eliminates the most common use of that swap file in the first place.
It might have an effect, if most programs that require the memory didn't use their own memory manager. But they do.
The only real benefit is when you set the flag on boot that allows all user space programs together to use 3 GB. That is, if you run multiple memory-devouring programs at the same time, that really use all that. And if you want to do it that way, just put 3 GB into your machine, hope your motherboard supports it, and turn off your swapfile. Because in that case, there would be no use whatsoever in having that.
And if Microsoft says differently, I would like some proof. Being a programmer and all, I think I have a pretty good grasp about how that is supposed to work.
