Why the awareness remove change happens more slower than add or update?

[nightire]

I noticed that the add/update changes of awareness happened almost instantly. For example, "user joined the room" or "user moves the mouse cursor." You can receive those types of change events immediately.

However, removing change events like "user left the room" did not occur as fast as adding/updating changes; you have to wait 10 - 15 seconds to receive the events on other clients.

Is this difference intended by design? How to trigger the remove events as fast as possible.
