How browser freezing can be avoided for 20K plus node unclustering

[tushersuvro]

Since you mentioned in one of your so post answer that after un clustering when large number of markers are loading on the map, it will freeze/hang the browser. It is indeed happening in one of my project where browser is getting hung for 30-40 second then loading all the markers ( 20k+ ) on the map. Do you have solution to this in the version of plugin and can you guide me on this? Also it would be nicer to have a loader which will be notifying the progress of un clustering. Thanks.

Hi,

Thank you for your message.
Please feel free to ask on Stack Overflow your help question next time, in order to reach a wider audience.

A simple way of preventing browser freeze is simply to disable the unclustering feature below some zoom level, when you know there will be too many Markers showing.

As for the loader, this would be extremely difficult, as the freeze is most probably purely a browser painting step, while the JavaScript thread is totally paused.
