But still you need a 4GB/4GB user/kernel split, because the standard is 3GB/1GB.

Why I need 4GB/4GB split? What are the beneficts?

Well... 4GB for your process is better than 3GB, that's 33% more space...

Right! So, the 4GB/4GB split and tmpfs pair should be the best solution to
address as much memory possible on a single user process.

If your process is cpu bounded (and not issuing too many system calls),
then 4GB/4GB split let it address more ram, reducing the need to shift windows in
mmaped files for example.

... any source code that explain better what you say ;-)!
