Dynamic Makers make map slow

[cuvant]

Hello,

Currently I'm working on a map app, and I decided to use MapBox GL JS API for the map. Currently I have an issue when I load the map on a big screen > 24inch. The map is lagging hard, and I have idea what may cause this.

I simply do a AJAX call on 'zoomed' event to fetch the locations that should be displayed in the maps view point.

Then I just loop through the GeoJSON and create markes and add items in the nabar.

You can see the behaviour here. Thank you :)

Can you quantify the performance you're seeing, or provide profiling data? Just glancing at the page you linked in Chrome, I'm not seeing the issue.

I think its very browser dependent - Safari, IE and Edge seem to have the problem but FireFox and Chrome are ok.
