Hello folks, we have a custom FORUMS menu which allows members to drill down to the forums they want. https://www.avforums.com/forums/ It uses an Ajax load calling the getViewableNodeList function in XenForo_Model_Node. It's a little slower than I'd like and I'm wondering whether this is as efficient as it can be for our specific needs? I.e. would a custom function speed things up? Any advice you could give would be very much appreciated. Thanks.
