[Just finished reading your paper, and hit the linux-mm.org site]

Good overview of the Linux 2.4 VM. Although I do
have some questions...

* When was the 'FREENIX' paper published? I could find
no date for it.

* What workloads would you recommend for testing whether
a VM is 'well balanced' or not?

* Would it be reasonable to have different 'default'
tunings for the kernel's VM based upon memory/swap
size/bandwidth? Personally, I feel that swap bandwidth
is an oft overlooked parameter in estimating VM performance.
