What about combining the idea of extra RAM and no swapfile by creating =
some
sort of RAMDISK and assigning the pagefile to it? Wouldn't this give you =
a
performance gain while also "feeling right" since we are all =
uncomfortable
with eliminating the pagefile since we know that Windows uses it even =
when
it is not strictly required.
I guess this also leading the idea of a solid state drive, i.e. TIGI, =
for
pagefile....

All true 9again this is just an exercise in "is it possible? And if so
beneficial?"
I mean if a server has a severe memory leak ot process that is eating =
memory
then eventually (4 Gb or 12) you will run out of working set/memory =
anyway.
So if you have a stable system and this an exception (an odd occurrence =
or
as Tim says something going wacky)and normally run WELL below your =
amount of
physical RAM it would be possible to run without a page file and see =
some
type of performance benefit. (again another "tweak")
I mean many of us have spent HOURS if not days trying small little =
tweaks to
get a tiny bit more performance, Since all of this little tweaks are
cumulative. What if something like this could give you a 1-2% boost =
with
very little risk.
I understand what Tim says (how it doesn't feel right) since Windows has
always relied heavily on the pagefile even when not needing it. But we =
are
working in a brave world here and I think I just might have to pilot =
this
change to see what's what. =20

I have to agree with Tim. There are basically two reasons that the page =
=3D
file gets used heavily in TS environments. One is that applications =3D
components get swapped to it (this is the problem that one of the =3D
optimizations in TScale addresses), and the second is that the OS makes =
=3D
sure that there is always enough working set available by "trimming" =3D =
pages
in memory that have not been used recently.
If you run without a page file, you will still benefit from TScale =3D =
because
you will have cut your total VM available from lets say 12 GB (4 =3D GB =
RAM +
8 GB page file), to just 4 GB, and the memory savings delivered =3D by =
TScale
will be all the more valuable to you. But, IF something =3D happens that
causes the need for memory to exceed your 4GB you will run =3D out of =
working
set. If you run out of working set, the OS blue screens. =3D Which leads =
us
back to the reason why it is good to have a large page =3D file - it =
ensures
that the OS has lots of places to put things so that =3D he does not run =
out
of working set.

Well you would save a little bit on all that page trimming activity. It
just doesn't "feel right" though. You would have no protection should
something go wacky. OK - maybe two things would have to go wacky - but
still...

Anyone ever thought of this. Lets assume you have 4Gb of memory on a =3D =
bunch
of Dual Proc boxes. You average about 1-1.5 TOTAL memory in use (page =
=3D file
and physical)=3D20 =3D20
With 2003 you can disable the pagefile and run from Physical memory =3D =
only.
Anyone ever try this or thought about it? I could see a benefit if you =
=3D
have plenty of physical memory saving the processor and disk cycles used =
in
paging (even though it is small).
