How can I speed up Ubuntu in virtual box? I've allocated 2 cores, 2gb ram, 128mb vram, 3d acceleration, installed guest additions, but it's still pretty slow. Moving windows around is really choppy, launching programs is fairly slow. It's not like my main computer's bad, the VM's just not using much cpu or ram at all. I don't know what the problem is. It runs about as good as it did on my old computer, which was much worse. I thought a far better computer would run a VM more smoothly.
Edit: I have tried running the vm with 4gb of memory assigned, but it made no difference at all, it's still choppy, and the experience was pretty identical. I'm not running games or anything, just simple things like terminal for most things. But when I want to use firefox, or something similar, or even just moving a terminal window around, it's just really sluggish and choppy.
