owl performance decrease linearly when adding widgets about owl HOT 2 CLOSED

Ok, this is interesting. A lot of the lost time was spent in the updateProps method. This mean that when we add 10k new widgets, OWL actually update the props of all other previous widgets, which causes a rerender. Implementing shouldUpdate in the Message component to return false make a big difference: 1694ms, 1970ms, 1901ms, 3093ms

Vue does not have the issue because it tracks of each component that needs to be rerendered, so it simply does nothing about the previous widgets, and React solves the issue by being extremely fast. It actually rerenders the previous widgets, but I suspect that its virtual dom is highly optimized, and uses object pooling to prevent useless allocations, and is in general quite efficient.

So, I consider this issue closed, Owl performance is actually pretty decent, especially considering that not much work was done on the optimization part.
