JMeter tips and tricks – Part 1

We plan to create a series of blog posts around Jmeter tips and tricks thatwill help performance testers to design some of the complex features using open source tool than having dependency on licensed tool . These posts will talk about the tips and tricks in using popular & open source load testing tool JMeter.

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.
