I have about 1800 photos in iPhoto under Panther, and I am experiencing severe performance issues. Everything in iPhoto is very very slow, even simple stuff like opening up a single photo in its own window. I get the spinning cursor of death constantly when using the application. I have an 800mHz G4 and 1GB of RAM, so I don't think that my hardware is _that_ out of date. Has anyone else experienced these problems (or better yet, have a solution)?
