“I’ve got 1GB of memory in my 867MHz PowerMac. But at 15,500 tracks, iTunes is starting to become difficult (not quite impossible) to use. It hums along fine if I don’t touch it. But simply selecting a track can result in 20 seconds of spinning beachball. Editing an ID3 tag can take more than 30 seconds. Dragging tracks to a playlist, same. […] iPhoto is even worse. At around 800 images, it started to bog down on me.” Read Scot Hacker’s editorial at OReilly NetWork. The book writer (mostly known for his ‘BeOS Bible‘ book, now a MacOSX convert) finds scalability problems on the famous iApps and suggests these to be fixed before adding new features.
