title: Setting time delay in logstash forwarder
body: <p>So recently I set up ELK stack with logstash forwarder located on two EC2 instances that forwards server logs to elasticsearch and kibana installed on another EC2 instance. Right after doing that, I recognized that the server CPU percentage keeps going up dramatically with the top process always being java (It is logstash-forwarder because the server is written in node.js). </p>
  
  <p>I thought about limiting the number of requests logstash-forwarder sends per minute. But first, I'm not sure if that is even doable from logstash-forwarder configuration. And secondly, if it is doable, is it better to send a bulk of log data rather at a one go rather than sending small chunks continuously? </p>
  
  <p>Thanks.</p>
