Yandex map | How to reduce the size of json data for the labels on the map?

Hi all.
There is a Yandex map with a bunch of labels on it.
The number of labels about 9000 and the volume of JSON data is about 6 MB.
What are some ways to reduce file size for faster display labels?

when the map is loaded and on change event scale, load only those labels that fit on the map.

+ make a limit on the number of points on the screen.

So you already have the solution, only you don't use it.
Depending on the scale of the return groups and single labels.
The scale has changed, to load the map of the new groups and single labels.
For you now the grouping makes "Yandex map"
