I have a Windows 2008 R2 fileserver in Hyper-V. Disk transfer times look fine with a few spikes here and there. But I'm not sure if the server has enough memory. I've google of course but I can't really find any recommendations about Memory Page Reads/sec counter. I remember that I (maybe) once saw a recommendation that it shouldn't go higher than 20. I'm hoping that someone could give me any input on this counter? I have an average of 175 over the last 10 minutes which is very high compared to the number of 20, but on the other hand task manager asys 3,5GB available memory, free is 0.
Or do I really need to dig deeper with other counters aswell to make simple analysis of whether or not the server needs more RAM?
