Due to some complexity in mojangs complicated chain of juggling whether or not a chunk should be unloaded when the last ticket is removed, many chunks are remaining around in the cache. These chunks are never being targetted for unload because they are vastly out of view distance range and have no reason to be looked at. This is a huge issue for performance because we have to iterate these chunks EVERY TICK... This is what's been leading to high SELF time in Ticking Chunks timings/profiler results. We will now detect these chunks in that iteration, and automatically add it to the unload queue when the chunk is found without any tickets.
