Apache Bench

The Apache software foundation offers a lot of cool tools. The one of them is Apache Bench. It gives you ability to test and get benchmarks of handling http requests by your web service. I currently use Ubuntu so to play around I ran next command:

sudo apt-get install apache2-utils

And fed my service to it:

ab -n 100 -c 10 http://127.0.0.1/greet

As a result, you'll get next output:

This is ApacheBench, Version 2.3 <$Revision: 1807734 $>
