Client-side high-efficiency optimization for real-time location system. There was a problem with a huge amount of messages through WebSocket channel about positions of all trackable objects. After some small amount of objects it start to have some freeze on client side because of overload main ui thread. I've created WebWorker for handling WebSocket messages about their positions, collect it to hashmap to overrite deprecated one and pass to the main ui thread only fresh data constantly each 250ms. After this improvement starts to be able to track much much more objects during one floorplan.
