    What are your performance issues?

    You should investigate your cache contents during the day. If the cache is stable you don't need to expand memory.

    Another solution is to "tune" your indexes. If you remove unused indexes SQL will consule less memory

    In order for Microsoft SQL Server 2000 Enterprise Edition to use over 4 GB of RAM AWE must be enabled. AWE is a set of application programming interfaces (APIs) to the memory manager functions that enables programs to address more memory than the 4 GB that is available through standard 32-bit addressing. SQL AWE memory is static not dynamic so when the SQL Server service starts it will reserve the memory specified as the “max server memory”. If there is 8 GB of memory on the server you will want to set the “max server memory” to 7 GB to allow 1 GB for the OS. The /PAE switch must also be included in the BOOT.INI file on the OS without /PAE AWE cannot reserve memory in excess of 4 GB. The /3GB switch should not be used in conjunction with AWE, but /3GB can be used in conjunction with /PAE on servers with more than 4 GB of memory but only running SQL Server Standard edition. The OS will need to be rebooted for any BOOT.INI changes to take effect.

    I wrote this article once.

    Important to know is that you can set all the switches and stuff ... but it's only useful for data caching. When on a 32 bit server, you can put whatever RAM you want, you'll still be limited for plan caching, sort space and lock memory ... :| .

    Thank you very much for your input.....

    Now, I have successfully implemented this and it seem better performance :)
