Thanks Shawn. I think the smp kernel that comes with 4.2.2EL can
handle upto 64G of ram. I have 4G. With RH9 it saw 3.6G, with Centos 4
it sees all 4. RH9 had a bigmem kernel which was smp enabled but the
2.6 kernels have a hugemem kernel. But then Centos does not have
hugemem, just smp (which acts like hugemem) so it can see upto 64G.
Mind you these 32bit kernels use tricks to access addresses over 3.6G.
True x86_64 does not have the performance hit that these tricks
require. Not to mention be able to address a *GIGANTIC* amount of ram.
