When I run VirtualBox If I don't use VirtualBox for some time and then I come back to using it the virtual machine runs very slowly, obliviously all subsequent operation go enough fast.
How I can avoid the memory manager to put the VirtualBox's process in the swap when the application is not used ? I want that application to respond quickly even after long time of inactivity.
NOTE: That question is not the same of:
Preventing a heavy process from sinking in the swap file Prevent an arbitrary process to use swap Prevent process from swapping (Windows)
because I don't have access to the source code of that application.
