How to display a large number of points on the map?

Question

Yandex maps

It is necessary to display about 3 thousand marks on the map at the same time.

1) We use ObjectManager (API 2.1) . The map takes a long time to load (from 8 or more seconds) and when fully loaded with brakes, it reacts to moving around the map.
2) We tried to implement the output of points through API 1.1 - the display speed has increased by 2 times and works without brakes .

Tell me, does the first version of the API really work faster or are we doing something wrong? We do not use clustering - the client is categorically against it.

I am attaching 2 screenshots with the implementation:
API 2.1

API 1.1

Answer 1

I would take another viewer and use tiles.
But since Yandex does not know how to tile layers - this is implemented on it through the ass: add only those labels that are included in the viewed area - maybe the JS array will be faster than internal data structures if you quickly wool over it, calculating whether the point is included in the view square.
