This guys knows their stuff pretty well. They helped me understand where my memory might fall short of my quota on my VPS and they optimized some CONF files that I needed modified for a much more robust server. I highly recommend them.

The Linux 3.8 Kernel Can Save A Lot Of RAM

For certain workloads with the Linux 3.8 kernel the physical memory usage is lowered by a significant amount thanks to improvements within this kernel that's presently under development.

This merge brings forth zero huge_page support, which as mentioned in the commit message, "Not a performance boost but it an save large amounts of physical memory in some situations."

The zero huge page support for the Linux kernel was introduced by Intel.
