There is absolutely no need to free buffers with so much totaly unused
memory around. 

99.9% memory usage is the most perfect runtime state, as much as
possible is hit through the buffer. Why not use the (very fast) memory
as much as possible?

Even 99.9% swap usage would not hurt if pages are swapped in/out very
infrequently.

Just watch how often swap and unbuffered-disk are hit, which can (but
might not) both be lowered with more memory. Disk is awfully very very
very very much slower than memory, so you want to use it as infrequent
as possible. Since memory is rather expecive, decide wisely... a server
just pumping out files from disk to network is probably also limited by
its network-link (very true for the gandi-case), so more memory will
never speed it up. Find your personal bottleneck and increase power
there first.


(not universially true, but for the quick and gerneral explanaition,
this should give you the right hints)
