web server Load testing tool [closed]

Question

Can you suggest a software tool (with GPLv license) to perform load testing for a Web server?

Answer 1

Curl will allow you to run through a sequence of URL quite easily. i.e.

curl -s "http://google.com?[1-1000]"

This will make 1000 calls to google i.e.

http://google.com?1  
http://google.com?2
etc... 

You can then add these calls to a script and run them consecutively as background jobs. There's a full explanation of this http://servermonitoringhq.com/blog/how_to_quickly_stress_test_a_web_server

Answer 2

1. Tsung is best I have used so far. You can create actual usage pattern.

2. apache benchmark is easiest to use and comes along with apache. Simpler to use,but is not flexible in terms of urls to hit for testing and creating more realistic load patterns.

Answer 3

Try one of:

• httperf (http://code.google.com/p/httperf/)
• ab (http://httpd.apache.org/docs/2.0/programs/ab.html)

Answer 4

If you need to do some performance/load testing also to web pages/apps, try Apache JMeter http://jmeter.apache.org/
