About 15 secs for CS3 the first time, but when I closed it to try it a

you first open the software, but it stays running in the background even
after shutting Photoshop down.

Perhaps but I think there's another reason also. I'd guess that a lot
of the I/O buffers used in the previous open are still laying around
untouched. Any time you can avoid an I/O by reusing a buffer cache it
saves a lot of time.
