That seems rather odd, and is contrary to what I've seen or
heard. Certainly, in the extensive VirtualBox or SVista
demos I saw, mentioned earlier, the greater amount of memory
being used (at least 4G.), clearly made a huge difference.
I saw various combos of XP, Linux, and eCS running inside
each other: that is, up to two guest OSes running concurrently
inside the host. Not just running, but running some of their
own apps. The performance was far snappier than I'd seen
such things previously, due to a faster processor and much
more Ram.

[SVista was a short-lived emulator solution for OS/2 | eCS,
which may have been developed by some of the former Connectix
people who worked on VirtualPC. I don't recall at this point.
I actually bought a license for this and have an install CD,
but never did anything with it, largely because I was given
to understand that better emulator solutions have come along
since then.]
