test5-pre1 VM best its EVER been!

test5-pre1 VM best its EVER been!

[Benjamin Redelings I]

Hi - I've been testing test5-pre1.  I have a UP PPro 166, and 64Mb RAM.

The last kernel that I tried was test3-p7, and it had some problems.  It
tended to swap when there was FREE (not cache) memory still available. 
Also, it never completely swapped out unused daemons, and tended to swap
out large running processes, like netscape.

test5-pre1 is wonderful.  I mean, both the stats from vmstat, free, and
xosview, and the interactive feel.  I can REALLY run both netscape and
quake and the same time!  The system rarely hits the disk - which is a
welcome change.  Things the you might hope to be in the cache,
apparently are...

The swapping really is incredible.  I have 20MB swapped out right now,
and only 5 of that is netscape.  Netscape doesn't even swap in, so the
pages that are out really need to be out!  In contrast, lots of daemons
(dictionary servers, translation servers, font servers) which take up a
lot of room, have RSS=4k, which I think is the minimum.  This is really
superb.

Thanks, to those who did all the great work!  
Stil awaiting active/inactive lists and other stuff :)

I am much less happy. My 128Mb system will not stop freeing memory (from the
buffer/page caches) until at least 16 Mb is really free. This means I
typically end up with 400kb buffer and 20M cached, which could be much
higher..... 

The swap behaviour seems OK though... only 8Mb in swap.

	This is the same problem that I had with test3.  So I guess its still
there, but is only visible on systems with more memory than mine.
