iPhoto - Resource Hog
I don't know what the deal is, but iPhoto is slowww. Oh, so brutally slow. For basic use or browsing, it's fine. For importing photos, it becomes a nightmare. iPhoto '09, version 8.1. (See signature for machine specs.) I had to transfer a full 700 even photos directly from the Nikon D40 this afternoon, and while it was transferring the 700, I had to walk away because the unit was unresponsive. (Activity Monitor: iPhoto = 99% CPU.) Even after the transfer was complete, iPhoto was hopping between 70-90% of CPU power.
Apparently, Aperture is more demanding than iPhoto, yet runs 2x better than iPhoto does on the same machine. (My library only has ~1400 photos. It's not massive.)
