Nice, If you have two arrays, you can improve system performance by moving
the Page file to the array that the OS is not on. But this only helps if the
arrays are truely on diffrenet channels. Same would would go for a normal
IDE drive

they are all 15000 rpm scsi drives in a raid 1 array they are quite fast
but
no where near as fast as ram. I think ill not tinker with what workes
fine,
just equip the servers in the future with 1500megs of ram instead.

It does seem like a waste of RAM, but that's how Windows manages
resources.
One thing to consider, Windows might be levearging your hard drive more
becasue of it's speed ablities. What type of hard drive(s) are you running
on your server? A good S ATA (while not nearly as fast as RAM) drive with
an
8 meg buffer could be the reason your not seeing a performance lag in your
server.
One simple way of forcing Windows to use more ram and less hard drive for
paging is to set you page file size and do not allow windows to manage
it's
own file size. But do keep in mind windows is designed to page data that
is
not needed out of RAM into the page file. Restricting your page file could
set off a bit of thrashing.
If you want to realy out do your self you could setup a RAM drive and tell
windows to use that drive to page to, but this was more of a prank pulled
on
co-workers :). It not that stabile and a great laugh to see the confused
look on someone face when they terminat that program using a mass amount
of
ram that doesn't seem to be doing anything.

Right, I do plan to have a test server to see any benefit if at all. Odd,
no
one commented on the -heapsize question.

Thats up to you, it will do no permanent damage, and unless
IOPageLockLimit is set to a completely arbritrary value it will also
remain stable.
Unfortunately there isn't at this point a completely definable optimum,
it is dependant on your hardware and software configuration and you will
need to test, essentially for, each new norhtbridge, as bus latencies
are the killer here.

Dunno, but it's easy enough to change the session manager options....
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session
Manager\Memory Management
In particular - the large system cache option will lift more of the
kernel into ram - this may or may not be advantageous - look at page
faults for your processes - might be a good idea to get pmon from
systeminternals.
disablepagingexecutive will page less data during general system run
time, this is not always an advantage as windows dynamic paging
algorithm is quite strong.
there is another option you can add here to change your IOPageLockLimit
(key not there by default), this allows you to specify the amount of ram
windows will allow for IO paging operations.

Hi all,
Just wondering about something. I have all windows2003 boxes and run
multiple instances of hlds and srcds. I notice for instance that if I
run
x
bumber of servers I am using 1.6 gigs of ram total, but only about 1000
of
that would be in the actual physical ram. The rest is is virtual. I have
2
gigs of ram per box. My question would be, is there any performance gain
in
trying to push more of the hlds/srcds process into physical ram? I dont
really experience any problems, but I would like to use the ram as
opposed
the virtual since I have it why not use it if there is a benefit. Would
the -heapsize switch help since I do not use it? Anyone out there know
how
to get windows to be more sparing with the virtual and push more into
physical ram? Why would the os want to use any virtual since im under
the
physical ram in the first place? Seems silly.
