    XMLWordPrintable

    Details

    • Database:
      Any
    • Difficulty:
      Moderate
    • Affected Branches:
      MOODLE_20_STABLE
    • Fixed Branches:
      MOODLE_20_STABLE

      Description

      The attached patch improves performance by not having to recursively search the admin tree each time a child is added. As an admin user, admin_category->locate can easily be called over 3,000 times! In my tests, this improved load times of an admin user's page by about 7%.
