Re: Pagefile size for 64-bit Windows 2003 Server
I think the KB is a pretty good guide on how to calculate
your page file. Try running the System Monitor as the
article suggests.
Extract from the KB889654:
"How to calculate page file size
Use one or more of the following methods to help you
calculate page file size.
Method 1: Use performance logs to understand the paging
activity on your computer
1. Click Start, point to Administrative Tools, and then
click Performance.
2. Expand Performance Logs and Alerts, click Counter Logs,
right-click the blank space in the right-pane, and then
click New Log Settings.
3. In the Name box, type a name for the log, and then click OK.
4. On the General tab, click Add Counters.
5. Click Use local computer counters.
6. In the Performance object list, click Paging File.
7. Click Select counters from list, click % Usage, and then
click Add.
8. In the Performance object list, click Memory.
9. In Select counters from list, click Available Bytes, and
then click Add.
10. In Select counters from list, click Pages Input/sec,
click Add, and then click Close.
11. Click OK.
Use the log that you collect during typical computer use to
understand the paging activity on your computer. Then,
adjust the page file size accordingly.
Method 2: Use the Page File Bytes Peak counter to calculate
page file size
1. Click Start, point to Administrative Tools, and then
click Performance.
2. Click System Monitor.
3. In the right pane, click + (the Add button).
4. Click Use local computer counters.
5. In the Performance object list, click Process.
6. Click Select counters from list, click Page File Bytes
Peak, click Add, and then click Close.
7. Let the counter run during typical use of your computer.
8. Note the maximum value for the Page File Bytes Peak
counter, and then multiply the value by 70. The sum of the
equation is the size to set for your page file.
Method 3: Calculate the minimum and maximum page file size
To determine the approximate minimum page file that is
required by your system, calculate the sum of peak private
bytes that are used by each process on the system. Then,
subtract the amount of memory on the system.
To determine the approximate maximum page file space that is
required for your system, calculate the sum of peak private
bytes that are used by each process on the system. Then, add
a margin of additional space. Do not subtract the amount of
memory on the system. The size of the additional margin can
be adjusted based on your confidence in the snapshot data
that is used to estimate page file requirements.
Note This estimate is accurate only if the snapshot of data
that is used to make the calculations is accurate."
