Michael,

There are only really 2 things to consider.

1. Will your server be required to page at all ??
If not then you can run with a minimal or no pagefile at all.

2. Will you want to catch a FULL memory dump in the event of a STOP event
occurring.
Is so then occurring will need a pagefile RAM x 1.5 to hold the dump.

Answer the 2 questions above and you can then decide on the pagefile size as
required by your app/sever.

Also see the following:--

DisablePagingExecutive

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
Data typeRangeDefault value
REG_DWORD 0 | 1 0

Description

Specifies whether kernel-mode drivers and kernel-mode system code can be
paged to disk when not in use.

ValueMeaning
0 Drivers and system code can be paged to disk as needed.
1 Drivers and system code must remain in physical memory.

Activation Method

To make changes to this entry effective, you must restart the system.

Setting this value to 1 is useful when debugging drivers, because all of the
code and data is always memory resident. It also improves performance on
machines with a lot of memory, because it prevents disk reads to get code or
data.
