Response is terribly slow, when using from/size for pagination for large 'from' values

The corresponding query nearly returns 3 million documents.

From : 1, size : 50 => Response comes within 2 seconds.
From : 1,000,000, size : 50 => Response comes after 20 seconds.

If we send multiple concurrent requests for the second instance, Elasticsearch instance hangs up. What are the possible approaches we can take in this scenario?
