I tried loading JSON then converting them to ol3 features (failed at 130k) then I used GeoJSON where I could load 150k data but zoom-in , zoom-out makes the map crash. Also, I have been using Clusters. How do I get around the problem? I can't use WMS since my only source of data is a JSON whose format can be modified. "}}
