I have a dual 2.0GHz PowerMac G5 with 4.5GB RAM running different installations of Tiger and Leopard. I have my main iTunes library on that computer and working with iTunes has gotten progressively slower over the last couple of years of iTunes updates. Playing songs work fine but editing is painfully slow. To "Get info" on a file can take anywhere from 2 to 5 seconds before the window appears. And when dragging a new song into iTunes, it takes a few seconds before iTunes is ready to accept the next one. My music library has 60000 songs in Apple Lossless and is located on a separate 2TB internal RAID 0 volume. Is there anyone else with a similar configuration who does not have this problem? Any other ideas?
