I have a VM installed on a 2012 Standard server. It has 16 GB of RAM allocated to it. right now it is running DHCP and DNS, it is a DC and SQL 2012 is installed. no other applications are installed. SQL is used for a electronic document storage application named PowerFlow. Based on their recommendation the maximum memory for SQL is set at 6 GB. The OS seems to be keeping a large amount of memory in reserve. Task Manager indicates that 96% is in use. This seems to be affecting performance of PowerFlow. It is very sluggish. I also installed Process Explorer screen shot attached.
