Hi there,
Immedately after the release of 2.1.63 I upgraded the
vhand patch to this new version.
In short, the patch does the following things:
- better aging on swappable pages
- introduction of page-aging for buffers, cached pages and
(starting with this version) shared memory
- alleviating the pressure on kswapd by making sure that there
is always something ready to swap out. It also acts as a
safeguard for kswapd. If kswapd bails out because of too many
consecutive failures, vhand will get called and it will make
sure that there will be pages ready to swap out very soon
ie. this patch improves swapping/paging performance quite a bit,
and (by fairer aging) also balances the various usages of memory
more fairly....
Because it doesn't do anything strange or critical, it can be
regarded as 'safe' for 'common household usage'. But then again,
if your livelyhood depends on Linux you won't be running 2.1.63 :-)
have fun, and see .sig,
Rik.

Send Linux memory-management wishes to me: I'm currently looking
for something to hack...
