Answer 1

We are aware of iTunes U sites that have created fairly broad and deep structures to include hundreds and even thousands of courses. This design of building a site is expected and recommended by Apple in order to help your user's experience of browsing iTunes U be as simple as possible. There are 2 problems that we aware of that come from this practice. First, the experience for Administrators can be slow and tedious due to the size of the site's main page and/or subsequent division pages. This problem may lead to a situation where iTunes simply renders a blank page when the Site Administrator logs in. Second, access to pages for end users can be slow especially if that structure is particularly large (in the thousands of course pages and tabs).
The iTunes U team will be working to resolve several issues that can arise from having sites this large and in the mean time we are recommending a few things that will help you plan your site and optimize its performance:
- Don't create empty courses and groups if there's no immediate need for them. Try to create courses and groups on demand. A large set of empty courses and groups can slow things down and will also clutter your user interface.
- We don't recommend more than 100 tracks per group. If you have a need to create a large collection of tracks that grows beyond 100 tracks, then we recommend creating several groups and subdividing your collection or using multiple course pages.
- We don't recommend more than 200 courses on one page. Again, if you have a need to create this many courses we would recommend that you subdivide. We will be working to resolve this issue in order to simplify and flatten the user experience for users that have access to only a few courses/groups.
- Clean up unused courses and groups and archive them outside of iTunes U. If you know a course from a previous session/semester/quarter is no longer being used, then you could delete it and restore it a later time if necessary.
