Ever since updating to iPhoto '11 it has become incredibly slow to launch. Using it is acceptable performance wise, but launching is terribly slow. I just closed it and reopened it to get an accurate time, and it too 3 and a half minutes! BTW, it only does the bouncy thing for a minute, then it just sits there. At first I ended up launching it multiple times because I thought it wasn't opening.

It is a 2.2 GHz Intel Core 2 Duo Mac Book Pro with 5 GB of RAM.

Everything else launches in an acceptable amount of time. Even iMovie is much faster. I have a fairly large library (75 GB), but it isn't any larger than it was before.

I've emptied the iPhoto Trash. Anything else I can do to speed it up, specifically launching?

Try rebuilding the library.

  1. Quit iPhoto
  2. Backup your iPhoto library
  3. While holding Cmd ⌘+Option, relaunch iPhoto
  4. Select the options to rebuild everything

Oh yeah, I remember seeing this before. I'll back things up try that. – Jim McKeeth May 5 '11 at 21:42
Interesting thing is after I ran time machine to create a full backup iPhoto is now fast again. Totally bizarre. – Jim McKeeth May 6 '11 at 18:44
