Thanks for this thread. I'm actually looking at the same settings for a
different reason. Most of our environment is VMWare-based and one major
difference between the Linux and Windows clients is how they use "free"
memory. Linux grabs it for cache ("Free memory is wasted memory.") but
Windows doesn't appear to touch it at all. This means the VMWare hypervisor
can over-commit memory.
