Hi all,

I'm running SQL Server 2005 Enterprise Edition SP3, on Windows Server 2003 SP2.

I have the following error messages

A significant part of sql server process memory has been paged out. This may result in a performance degradation. Duration: 0 seconds. Working set (KB): 36492, committed (KB): 104768, memory utilization: 34%.

Is it recommended to set 'lock pages in memory' to stop this paging?
Or should I do some analytical work beforehand?

Lock pages in memory keeps the pages in memory and doesn’t allow the OS to page them out. It is possible performance is improved – but does require testing.
large page extensions can also be influenced read on : http://www.sqlserver-dba.com/2012/05/cannot-use-large-page-extensions-lock-memory-privilege-was-not-granted.html
