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 ;-)!
