The Itunes store takes forever to load a 1.5 minute song preview, and in the middle it still gives 'Opening URL Buffer stream' dialog box. I have tried
defaults write com.apple.iTunes buffer-stream-size 128000, tried 256000 and 64000 but I still get the same problem. My internet connection is not to blame. How do I speed up the loading?
Edit: This is itunes version on a 13 inch macbook pro running Yosemite 10.10.4. App store takes really long as well to load pages.
