Some findings for our references: When using FeatureLayer for plenty amount of data (e.g. vast amount of points), ArcGIS JS performs better than Leaflet. So even the file size of Leaflet is far smaller than ArcGIS JS, I still have to choose the larger one. Hope Leaflet FeatureLayer performance can boost up in future.

Multiple AsyncTask execute() actually execute the tasks sequentially. If the previous task takes a long time to run, the next task can only wait till the previous one finish. To have a true parallel run, use the following instead of AsyncTask.execute() :     AsyncTask.executeOnExecutor(Executor exec, Params... params)
