I've got what seems to be a cache memory problem with my Server 2008 machine. The machine has two quad core Xeon processors and 24GB of memory. The problem is that the server seems to cache an awful lot of memory, making the server very slow and unresponsive. I've been all over the internet looking for a solution...hopefully someone can help! I've attached a screen of Task Manager with the cache amount highlighted.
The server's main job is Hyper-V. There are 4 virtual machines on this server. Each virt has 4GB memory and one of the processor cores allocated to it. This should leave 8GB memory and four cores for the host OS. The server also has a small file share located on it. That share is less than 75GB and is not accessed that often. As I said, the main problem is the slow response of the host OS. To manage Hyper-V, we have the System Center Virtual Machine Manager console installed. Sometimes it can take, no joke, 5 minutes for the console to open. Very frustrating.
