I think you are experiencing the difference between RCP and DAAP. When DAAP (iTunes) needs the track listing, it doesn’t return until it has received meta data for all of the tracks.
On my setup (approximately 8000 tracks), it takes close to 50 seconds after clicking on the libary in iTunes before I can see the tracks. On the SoundBridge it returns in less than 5 seconds.
I don’t think there’s anything that Ron can do about this…it’s just the way that Apple has implemented DAAP sharing in iTunes.
