I have about 9200+ photos that are managed by iPhoto (9.4.1 / the latest and greatest version in the App. Store) and I find the performance of iPhoto while starting up and shutting down is degrading. Especially while shutting down. The photo database by itself is around 44GB. How do I improve performance? I have an 24inch iMac from 2010. Does Aperture work better or does any of the Adobe products (the reasonably priced ones) work better?
