How we can inctrease node js performance : Req/sec

I have developed a product using nodejs as backend. When I hit the API using benchmark i get this result :

That is 190 req/seconds (approx). I want it to be like 4000 or something per seconds. How can we configure our nodejs to achieve maximum performance.

I have tested it on local host ( Macbook Air 4GB Ram) and on linux server.
