I have read loads of threads about iPhoto being slow, both here on MR and also on the Apple support discussion boards. Sorry for starting another but I know this problem is really annoying to a lot of people. I'm using an iBook 1.2GHz with 768Mb RAM and a 60Gb hard disk. I have about 15 Gb free on the disk. I'm using the most recent versions of Tiger and iPhoto 5. I have about 6,000 photos in my iPhoto library and I wanted to add about another 2,000 after scanning a lot of old paper photos. These are currently stored in folders on my hard disk. I have about 4,000 of the photos in my library organised into about 100 albums, one for each event. Before I start to import the new photos, I did some simple organising of these albums in iPhoto. Basically I created a folder for each year (going back to 1992) and then moved all my albums into the relevant years. The folders fo 1992-2000 are still empty as these are for the scanned photos that I want to import. I didn't delete any photos. I didn't add any photos. I didn't edit any photos. I didn't add any photos to albums. I certainly didn't do anything to the iPhoto library from the finder. I simply put my albums into folders to organise them into years. Ever since I did that, iPhoto has been very very slow. I can't do anything without getting a spinning beachball for a minute or so. I have tried restarting my iBook, repairing the disk, fsck etc etc and nothing has helped. It seems to me that iPhoto is not robust enough to be useable as a photo management tool. Its driving me nuts, because I really like iPhoto, but it just doesn't work reliably. I am considering installing iPhoto Buddy and making each year a separate library. I'm sure this would help, but I don't want to do it unless I have to. If I do use iPhoto Buddy, does that mean that I can't search by keyword (or use smart folders) across different libraries? That would be a major flaw to me. Now that I have written all this, I feel a little better and less stressed with this. But iPhoto is still not useable for me.
