Hmmm. That should be next to instant on either system. I wonder if something
is simply configured badly and introducing a delay.

I'm going to make the assumption that you're not running a heavyweight GUI
environment such as GNOME or KDE. In that case, the greater RAM is probably
not usually a factor at all. And the Celeron 700 is a very low-end chip with
pretty low overall performance.

On the other hand, either machine ought to be able to do better than that.
