Why does sql server use no more than 500mb in ram? We have sql server 2005 running on server 2003 32bit with 32GB of ram and in the task manager under processes, Mem Usage sqlservr.exe is only using 430, 268 K. SQL Server min memory is set to use 25GB and max is set to use 29GB. Our database is 500GB in size and our PAGEIOLATCH_SH is high. I dont understand what is going on here. Also we have been having HIGH CPU usage.

SQL Server 2005 Express SP3 Memory Usage

Upon Startup of my system the sqlwriter process immediately grabs 700mb of RAM and holds it. As I use the SQL Server to do different thing the memory usage grows and causes the memory on my system to decline. The SQL Server never releases the memory and it causes my system to respond slowly. I fear that if left unchecked it might cause the system to freeze.

Memory overhead recommended for benchmarking SQL server 2005 on vSphere

SKrep — Fri, 31 Jul 2009 20:09:46 +0000

For a ‘direct’ physical to VM comparison of SQL server 2005, would anyone recommend giving the VM extra (say, 1.5GB) RAM to compensate for any overhead the OS needs? So a direct comparison would then be 1vCPU, 2.5GB RAM VM & SQL set to use 1GB RAM) vs. SQL on physical host set to use 1CPU and 1GB RAM.

Upgrading to a 64-bit SQL Server 2005 environment

SQL Server Ask the Experts — Mon, 02 Feb 2009 18:28:28 +0000

We are replacing an existing SQL Server 2005 32-bit environment with a new SQL Server 2005 64-bit Enterprise Edition environment. The new solution will be a 2-node Microsoft Cluster with SQL Server Cluster Server, all 64-bit Enterprise additions. The only issue we are having is determining a good baseline for the base memory to install. Can you suggest a minimum amount of memory to handle the 64-bit OS, application & two or three instances?

SQL Server 64-bit Memory Requirement

We are replacing an existing SQL Server 2005 32-bit environment with a new SQL Server 2005 64-bit Enterprise High availability environment. The new solution will be a 2-node Microsoft Cluster with SQL Server Cluster Server, all 64-bit Enterprise additions. What I have a problem determining is what is a good baseline for the base memory to install. I will assume that the 64-bit OS & 64-bit SQL will require more memory than the Win2k3 solution. Currently we have one instance but we anticipate adding more instances later (probably 2 more). The servers have 8 GB but I fear we may need more. Can you suggest a minimum amount of memory to handle the 64-bit OS, APP & 2-3 instances?
