I started using Macintosh as my own work machine at home since Year 2008,
& until now I have more than 150 GB of Hard Disk space occupied by iTunes Library folder.
I was just thinking out how to utilise iTunes library with mire efficient way than just loading with 50 GB of podcasts, 50 Gb of iTunes U & 20 GB of songs, 30 GB of Movies
I just reached one solution which I implemented immediately by splitting iTunes Library in two different folders one for only Music & second for other stuffs like Movies, Podcasts, iTunes U etc.
Here is the catch as I determined I never use Podcasts & iTunes U every day or every hour it is just for reference & help only material so why to put heavy load on primary drive called ‘Macintosh HD’ so I relocated second library with podcasts, movies, iTunes U to external drive….
& Suddenly my Mac is running as fast as before than 150 GB of iTunes folder on primary or OS Boot drive…
Hope it helps…
Thanks & Regards
