How to achieve the display of a large number of points on google maps?

Question

JavaScript

I am displaying a large number of markers > 2000 on the google map using MarkerWithLabel.js, for the convenience of displaying markerclusterplus.js clustering is used. I hoped that there would be less brakes with clustering, since thousands of markers would not be displayed on the map at once. But it got really bad. I found an excellent example of a solution - map.gdeetotdom.ru/#10/55.8275/37.6117
As I understand it, our own developments are used here, how would we take such an option for ourselves?

Answer 1

Here, counters are simply loaded via ajax, and the points themselves are displayed at maximum zoom.
Therefore, it works more smoothly (although it’s somehow twitchy, as for me the map / flags are moving, more precisely parallax)
