Hi All,<br />
<br />
Just wanted to get a feel for the amount of physical ram that should left free for the operating system.<br />
<br />
The case in question is we have a large &nbsp;Windows 2003 r2 ENT x64 server that houses 500GB of Ram. It runs a Data warehouse\BI application that stores all of it's cubes in memory. It only writes\reads from disk during start up and shutdown. It chews through the memory depending on the number of Cubes loaded.<br />
<br />
We are having some performance issue, and I'd like to rule out memory starvation as a cause. While I'm running a perform trace, I would like some suggested guidance on how much free memory (non paged, aval MB) I should be looking for before I start making noise about memory issues.<br />
<br />
Thanks for any advice in advance.<br />
<br />

How Much Physical Ram to Leave free

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
