I have to agree with Tim. There are basically two reasons that the page =
file gets used heavily in TS environments. One is that applications =
components get swapped to it (this is the problem that one of the =
optimizations in TScale addresses), and the second is that the OS makes =
sure that there is always enough working set available by "trimming" =
pages in memory that have not been used recently.
If you run without a page file, you will still benefit from TScale =
because you will have cut your total VM available from lets say 12 GB (4 =
GB RAM + 8 GB page file), to just 4 GB, and the memory savings delivered =
by TScale will be all the more valuable to you. But, IF something =
happens that causes the need for memory to exceed your 4GB you will run =
out of working set. If you run out of working set, the OS blue screens. =
Which leads us back to the reason why it is good to have a large page =
file - it ensures that the OS has lots of places to put things so that =
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 =
bunch
of Dual Proc boxes. You average about 1-1.5 TOTAL memory in use (page =
file
and physical)=20
=20
With 2003 you can disable the pagefile and run from Physical memory =
only.
Anyone ever try this or thought about it? I could see a benefit if you =
have
plenty of physical memory saving the processor and disk cycles used in
paging (even though it is small).
