The last couple of weeks I’ve been playing with a load testing tool called Blitz. You can create a free account which provides you the ability to ‘rush’ your web application with 250 concurrent users (or less) for 1 minute. And of course, you can increase both the number of concurrent users as well as the duration of the load tests after you specify a credit card number.

The interface is pretty slick, as it provides you with a kind of command line interface.  


Here I specified to run a load test, increasing the number of concurrent users from 1 to 12 over a period of one minute. The test is going to run from their datacenter in Ireland. You can choose from a couple of places in the US as well.

This command yields the following results.


Blitz also integrates with web application performance tools like New Relic which enables you to further analyze the results and see what’s going on in your web application.

This is actually the first time ever that I had so much fun doing load tests Winking smile.

Until next time.
