Hi, I have a 8GB RAM server running SQL Server 2008 Enterprise Edition. I have allocated 5.5GB RAM to SQL Server. After some normal queries start hitting the server, the RAM used by SQL Server is goes up to 7.2GB. The strange thing is that the memory usage by SQL Server was not dropping and it kept maintained at 7.2.GB. I am wondering, is this is the expected behaviour of SQL Server 2008? I don't think SQL 2005/2000 behave similar way? Are the something that I need to turn on / off in order to see the correct behaviour. Thanks, Goboxe.
