Maybe using the commoncache module can speed some things up. Like keeping cached data of the json request for an hour or longer

I will have a closer look to commoncache but if you have set up parameters for display only unwatched movies for example, each time the script is called, I have to scan all the playlist/library to seach for unwatched movies. And what's happen when you add a new source to your library ?

Is there a way to have the script run after certain events e.g. on xbmc startup and after a completed library update? Currently everytime you go to the main window it will run the script. This isn't terrible if you only call the script once and are hardwired to your network but more than a few calls and wireless it gets painfully slow with a large library. I completely understand that the script scans through the entire library which will lead to slowdowns but maybe this could help alleviate some of the issues?

Maybe there is a JSON method to known if database has been updated, I will ask to the specific thread.
