I am having a performance issue with my SQL reporting server, when I got to the server it shows 92% memory are used in total. so I checked detail which process were using so much memory, but nothing too big, so I sum all the memory usage listed in the resource monitor, and the total number is about 600m, and my server has 4G memory. Is there any way to check where is my memory? and which process are using it?

I would have ask here. http://social.msdn.microsoft.com/Forums/en-US/category/sqlserver Thanks

Hi Myousufali thanks for your reply. Since the memory usage of SQL service is normal, so I would think it should be a general issue of the Winows 2008 server R2.

Hi, SQL services are designed in such a way that it takes most of the memory of your system, so this seems normal. Thanks, Swapnil Prajapati
