I've had my iPhoto library on a Drobo for a few months, all has been fine. Recently upgraded to iPhoto '09 and performance is terrible. It takes 5 minutes to open iPhoto. The Faces feature causes constant beachballs. Overall it is just very sluggish. Is this just '09? Or '09 combined with the external drive? I have 15,600 photos in my library. Any tips on how to fix these performance issues. I have a white C2D 2.16Ghz iMac with 3gb RAM. Drobo is on FW 400.
