But again, there is no excuse in doing this each time you need a tree. Thanks to system notifier we have a ways to determine when category tree needs to be rebuilt, so it can be built once and stay cached until user add/remove/rename category.
yes, right. Packages are cached for a long time and also their classes and extended classes. And now also the class cats per package, which is a small share though. But it's good to cache iy anyway.
Also, note, that you need only one instance of such tree in image . You don't have to build this tree over and over again for each browser window on screen :)
