On a `MacBook5,2` running `OSX 10.5`, with only `2GB RAM`, [Alfred](http://www.alfredapp.com/) toggles *very* slowly, like up to 5 seconds after the keystroke.
After I've *just* toggled it, it will toggle again much faster, but after a while it will be slow again.
What can I do to identify and fix the problem?

IIRC it does that even with the computer just started, so it's unlikely it's already swapping, but I'm open to suggestions.
