Vidar,

The performance depends on a few things:
- how complicated the lens templates are - see if you can simplify them, 
use CSS classes instead of style attributes.
- how many facets there are, and how many choices are in each facet - 
avoid using facets whose choices have counts of only 1.
- how many items are shown - add ex:showAll="false" to your tile and 
thumbnail views so that only 10 items are rendered at first.
- of course, the machine on which you're viewing the exhibit.

And when you said performance, did you mean the load time or the 
interactivity?

Exhibit 2.0 (warning: not released yet) has been sped up a little bit, 
might be noticeable if you have lots of facets. I personally haven't had 
much problem with the map view being slow. How's this exhibit working 
for you on your machine?
