It rocks!

Some iPhoto users will take long to open or perform any task, but fortunately this can be solved very easily. Only you have to do the following:

1. Open Terminal (in Utilities)
2. Write on the Terminal cd (put a space after the word cd) and then drag the Terminal window iPhoto library, should be written like this:

cd "~ / Pictures / iPhoto Library"

1. Press enter
2. Important! Close iPhoto
3. We write in Terminal the following command and press enter:

for dbase in *. db; do sqlite3 $ dbase "vacuum;" done
Now your iPhoto should take less time to open and all other actions in which took too also should do something faster. This proven to work both iPhoto 08 and iPhoto 09

If you did not have these problems do not need you to do this little trick, but not proven that nothing bad will happen to do so provided you follow the instructions to the letter.
