How to improve the performance of a virtual machine?

Question

Amazon Web Services

There is a virtual machine (instance) from Amazon. Vin Server 2012 R2.
From time to time it is very buggy, it is impossible to work. The most interesting thing is that sometimes everything is fine. What can I see, why is this happening and how to fix it?

Answer 1

As an option, loads on your local machine are possible, as a result, virtual glitches occur. It can be anything, updates, etc. maybe even a virus. As far as I remember, virtual machines do not block that part of the RAM that you slipped into it, and if the local machine needs it, it will select this memory for its needs, the virtual machine may hang from this.
