Typically no more than 3 or so at any given time. Outlook, Word, Edge, a Windows-only utility or two. Pretty light load, being all interactive.
So I give the VM a few CPU cores and 4GB RAM and it does okay.
If I was loading them down, doing software development or running lots of database stuff, I’d have to allocate 4 or more cores and at least 8GB RAM, to get decent performance.
Thanks. Do you know what percentage, roughly, of Windows applications would run in it okay? I am wondering, for example, about the Finale music scoring app.
