Use ApacheBench test HTTP performance.

ab（ApacheBench）is Apache http performance test tools.

 

Case: Send 10 concurrency requests to open index page at same time and run 100 times.

 

Input the below command at CMD shell: ab -n 10 -c 10  http://10.136.4.22/

 

The result will be show as below:

C:/Program Files/Apache Software Foundation/Apache2.2/bin>ab -n 100 -c 10 http://10.136.4.22/

This is ApacheBench, Version 2.0.40-dev <$Revision: 1.146 $> apache-2.0
