Perspective map lags with large amount of features

Hi all,

I’m trying to build a project to monitor marine traffic so i tried using the free open-source marine traffic data from Marine traffic | Digitraffic - Fintraffic. I faced serious lag issue in the perspective map when using the browser and even in the designer mode. I believe it might be due to large number of features loaded in the perspective map.

I need help to optimise the Perspective map. Would there be a better way to load the marine traffic in the perspective map like what we can see in the marinetraffic.com?
