Hi all,

I have a customer with 12GB RAM running sbs 2011 with a 25GB page file. Is this normal?

If not what are the steps that need to be taken to:

A) Reduce it

B) Prevent it from happening again.

Thanks in advance.

Typically the pagefile is set to physical ram x 1.5 (so it should be 18GB).

Actually the rule is 1.5 to 2 times the amount of RAM.   You don't indicate how many users are on this server but 12 GB is pretty low and so you may benefit by the larger page file.

The best measure for determining the correct size of your page file is Perfmon and checking for percent of pagefile being used.  If it's more than 50%, you need more RAM

If the page file is currently on the C: Drive and you're hitting a disk space issue on the C drive, you can move the page file to another partition.  If it's actually a different physical hard drive, you might see a slight performance increase too

Hi,

There are 26 users, and we were initially exploring free space running out which lead us to this. Cleared out some logs and thats fixed now. Was just wondering if it was something to be concerened about.  We've got 30% used and following what everyone is saying I dont think we'll bother changing it yet.

For my customers with that number of users servers have a min of 16gb of ram, but more often 24 or just max the allowed RAM of 32.  Single biggest performance improvement gains are by adding RAM
