memory setting in SQL 2005 in Windows 2003

We have a SQL 2005 installed in Windows 2003 64 bit system, which has 16 CPU and 32GB RAM, but the performance is poor. SQL server is AWE enable and the sql start account with "Lock Pages In Memory". I checked the task manager and it looks that the SQL server used only about 300 MB memory. Here is what I found:

What I need to do?

Thanks

Sounds like you have installed the 32 bit version of SQL Server, not the 64bit version of SQL Server.

Can you verify which version of SQL Server was installed?

If I recall, AWE has no effect in 64 bit OS, and extended memory usage is not properly captured with Perf Monitor.

Please refer to this article:

Configuration -Memory, 32 bit SQL 2005 on 64 Bit Windows 2003

And for reference on Memory, this is good starting point:

Hi Sandlu,

AWE will have no effect on 64 bit servers.

Yes you still need "LOCK PAGES IN MEMORY".

To check exactly how much memory is being used by SQL Server use Perfmon to check for SQL ServerMemoryManager:

Total Server Memory (KB)

Also check if you have capped the memory by using Max Server Memory under sp_configure.

With regards to slow performance, it could be any problem like disks, memory or no/out of date stats or Index defragmentation.
