      (This is a 'check it isn't broken' test as there should be no functional change.)

      1. Browse around a few pages of the site including a course view page.
      2. Turn on the performance information and check that the cache information shown at the bottom of the page still looks plausible.

      Description

      The get_from_persist_cache function could benefit from optimisations:

      1) Where perfdebug is turned on (some live sites used this option), record_cache_hit takes an annoyingly long time.
      2) Micro-optimisations could improve performance of the main function.

      I'll give details in comments.
