Opening VM settings dialog takes too much CPU and time

Description (last modified by frank) (diff)

In the VM Manager, if I click on the Settings button, I can see CPU usage is very high for at least one second.

Although one second is a very small amount of time, but it does not feel good. And why does it make my CPU busy just for displaying a dialog?

It is not just open an dialog. VirtualBox uses COM for all its internals. All configuration items have to be fetched through IPC. Additional the availability of all configured disks is checked too.

We are working on improving the situation but there is no ETA as the fix is not trivial. This will happen mostly for installations with a lot of registered mediums.
