Hello Linux,

2.4.xaa Series as well as SuSE kernels have 3.5G userspace option,
which seems to be quite useful, therefore I see it's not included
is stock kernel for some reasons. Also I've heard this
configuration may have some performance problems.

Can anyone comment on this topic ?

I need large amount of address space for my application but I also
need to get as much I/O performance as it's possible, so I can switch
to 3.0/1.0 memory distribution if it will benefit here.
