Explanation
The most likely reason why users are not experiencing any performance benefit after upgrading the memory of their on-premises VMs is that the operating system has a memory limit that prevents it from using more than
8GB of RAM. This could be due to the operating system version, edition, or configuration. The systems administrator should check the operating system settings and requirements and adjust them accordingly to allow the VMs to use the full 16GB of RAM.
