How to simulate bandwidth in JMeter?

  • Go to JMeter_HOME/bin folder, open jmeter.properties
  • Search for httpclient.socket.http.cps=0
  • Uncomment that line and enter your desired bandwidth to simulate
  • If application is under https protocol then uncomment httpclient.socket.https.cps=0
  • Before entering your value in CPS (Character per second), use the below formula to convert kbps to cps.

Formula: (desired bandwidth*1024)/8

E.g. if desired bandwidth is 100 kbps, then cps would be 12800

Summary:   When we want to run test on local LAN but need simulation of internet bandwidth or wireless bandwidth, the above solution is helpful.
