How to limit the rate of HTTP requests?

I am using async.eachLimit to hit 30 parallel requests on the server using request module. The problem is server CPU usage is reaching at 60% and I want to keep it low. So I need to limit my http requests so that it hits only limited number of requests on the server?I found a similar problem on stackoverflow and the accepted answer is using a timeout. Is there any other better way to do this?
