I have a problem with zooming in/out to a large number map points in highcharts map.
First of all, I follow this guide:

[https://www.highcharts.com/demo/maps/mappoint-latlon]

After, i export my own Custom GeoJSON map following this:
[https://www.highcharts.com/docs/maps/custom-geojson-maps]

And in the end, i insert a lot of map point with lat/long (n.1505), and here’s the demo:
[https://jsfiddle.net/mco29/k480sLhb/22/]

I added the turboThreshold, also set animation to false, but nothing happened. the problem is the performance of zooming in/out (very slow).

Any ideas ?

Thanks
