Why Parallels so slow on one computer and not another?

When I installed Parallels with Vista on my new Macbook, it ran (runs) perfectly with no noticeable slowing down of my computer.

When I installed Parallels with XT on another, slightly older Macbook, it makes the computer run at a snail's pace no matter if I am working in a Mac program or a Windows program. Why does Parallels run so slow on this computer and is there any way to speed it up? Its specs are:

Processor Name: Intel Core 2 Duo

Most probably the memory. If your XP is set to use 512 MB or more, too few is left for good performances on Mac OS X side.

The newer configuration has most probably 2 GB or memory instead of 1. Solution: just add memory to upgrade it to 2 GB.
