Lightroom performance

Several years ago I needed to split up my lightroom catalog, primarily 
into "everything" and "working", because trying to get things done in 
the everything catalog was too slow to be practical.

I'm not certain, but I think that the performance doesn't deteriorate by 
the number of photos, but by the number of collections.

There does not, however, seem to be any efficient way of doing 
maintenance on the collection list.  It does seem to help to remove the 
photos from a large collection before deleting that collection.

I suspect that the problem has to do with when you do something to a 
photo, you then have to go and look at all of the collections it is in 
and modify something there. Similarly, if you delete a collection you 
have to go through and check all of the photos it is in.
