Lately I have had to reboot my windows 2012 server as my shared folders are very slow.

When I look I do not see high CPU or memory use.

Generally average about 25-40% peaks while I look.

I already have monitoring on CPU and Memory is there another monitor I can enable to better track the health of my fileserver to get to the bottom of this issue.

Once I reboot everything is fine but I am not sure what is causing the slowdown.

Thank you
