From time to time, as a web developer you may want to run http load tests against a website to make sure it can handle adequate traffic. An excellent software for this is Siege. So, first, install Siege. On a Mac you can do this using brew as follows:
brew install siege
Once installed, run your test using a command like:
siege -c 10 -r 5 -b http://somesite.com
This runs 5 requests on 10 concurrent connections against somesite.com.
