1. Re: Limit on catalog size?
areohbee Jun 14, 2014 5:58 PM (in response to ronze98)In general, the fewer catalogs the better.
Big catalogs do affect performance of some things, but size should *not* affect performance of develop module or viewing photos in library module. What big catalogs can slow down is time to update smart collections, lib filters, or whole-catalog metadata displays... - things that require visiting all photos in the catalog. Develop module just works with a single record (or small set of records), and it's as efficient with a million photos in the catalog as with a thousand. Same for library module when you've got a folder or collection selected - the other records in the database are simply being ignored - not slowing anything down..
If you *do* notice something slowing when it shouldn't, as catalog grows, it's typically due to some other problem with the catalog besides sheer size (or it's not the catalog at all..).

dj_paige Jun 15, 2014 4:27 AM (in response to ronze98)I agree 100% with Rob. Also, people in these and other forums have reported Lightroom catalogs of over 1/4 million images that are working well.
