json response is very slow.

May 2 2017 5:56 AM

Hello, I have a json API: "https://web.fulcrumapp.com/shares/ee99463260c9cf3d.json"

Their are only 216 reords (4 columns) now. But When I am fetching these records and shows in datagrid, It takes 20-25 seconds to display. Their should be 1000s of records in future. Client is complaining about it. What can I do? Please help..
