Long loading time with large JSON object.

It's taking a long time to load a large JSON object into the plugin. Is there a way to optimize the plugin to increase the speed?

Can you upload your JSON file? So that I can test it.

I have a 1 MB JSON file and it takes a longtime to load even if I set the collapsed option to true. Is it possible to lazy load the json file instead of loading it all in one go.
