Distributed parsing

Distributed parsing

Distributed parsing is another way to increase performance of the tree with some levels containing more than 100-200 nodes per level was introduced. The main advantage of it lies in making the level visible and ready to use before it is completely parsed. Thus, items are loaded portion by portion with some timeouts.
