What happens after a reboot? Is this disk cache? The operating system knows how to handle memory, and it usually does it good. If you're worrying about performance, look at the page hits as a much better indicator of memory overcommit. You can verify that using RamMap , from Sysinternals. Look for "Mapped File" in "Active" state. Sign up to join this community. The best answers are voted up and rise to the top.

Asked 12 years ago. A metafile is a part of the system cache containing NTFS metadata and used to increase the performance of the file system when accessing files. For each file or folder, accessed by the users, a corresponding block of at least 1 KB the record of an attribute of each file is 1 KB, and each file has at least one attribute is created in the metafile.
Thus, on file servers with a large number of files, the metafile size NTFS cache may exceed several tens of gigabytes.
It is impossible to disable this cache or manage it using built-in Windows tools. As a solution, you can increase the size of the memory on the server, but it is not always possible. To free up memory, you can restart the server, but in some time the size of the metafile in the memory starts growing incredibly.
For example, you can estimate the size of the MFT using another tool by Russinovich — ntfsinfo. The main disadvantage of this method is that the clearing is manual and cannot be done automatically. It is rather easy to install DynCache there are detailed instructions in the archive.
These and other DynCache service settings have to be edited according to the RAM size, the server load, required performance, etc. As a rule, it is not recommended to set the cache size more than half of the physical RAM installed on the server.
Only one virtual machine will be installed and used to test disaster recovery restores from image backups of servers, when done testing the VM can be removed so we can test another server.
The other servers are similar or less powerful with less memory. I am not planning on creating a partition for this. We have plenty of space on our RAID drives for now. We use two domain controllers in our domain. This is perhaps the biggest reason why we should not also have SQL server installed and add the Hyper-V role.
Thus we plan to buy a 'bare-bones' refurbished Dell server to test disaster recovery and not use Hyper-V at all. This keeps the testing of image restores off of our production server which I think is wise.
That depends on your server and the roles installed and if you open the Hyper-V management console or not. In your configuration with a freshly booted server where you have not opened the Hyper-V management console, it would likely be in the range of MB of active memory and practically no CPU probably closer to 10 than A good way to get a pretty good figure for your set up is to boot cleanly with no VMs running and check the memory free then stop the Hyper-V services and check the amount again.
Disable those services, reboot, check the amount of memory, then finally start the services and check the amount again. The different between the first two and second two numbers will give you a good idea of how much just Hyper-V takes in your configuration. Hyper-V Memory use goes up with usage but the basic Hyper-V service is mostly just running instances of vmwp. One vmwp. A good way to figure this amount is to boot cleanly with no VMs running, note the amount of memory free, then start a typical VM.
Wait for that VM to finish booting, not the amount of memory free again, then log into the VM, and finally take another look at the amount of memory free in the server. The different between the 3 should give you a good idea of what's being used. Hyper-V is essentially the services and some processes that execute, 1 per VM. Each VM runs inside an instance of vmwp. Those will shut down when you stop Hyper-V.
NOTE: These names are different under server
