Let me rephrase it, can we compress the data that is coming from jsreport render function?

Browser displaying the html takes time.

Hi,

We are calling a jsreport render function which use good amount of JSON data and recipe is html. Its return bodyBuffer and then we are converting that buffer to string and passes to iframe tag in srcDoc attribute. It shows loading icon on frontend and taking time to render on frontend side.
It seems that the response i.e. bodyBuffer is large which return from the server to frontend. Can you guide us on this with respect to performance ?

Thanks for your help in advance.
