The Future of Performance Testing

Alex Podelko

Following up my post Are Times still Good for Load Testing? , I decided to answer multiple comments here separately. First, I’d like to elaborate on “It may be less need for simple load testing due to increased scale and sophistication of systems” I meant that the traditional way – testing the system before deploying in production using production-type workload – is not the only way anymore.

Are Times still Good for Load Testing?

Alex Podelko

My post Good Times for Load Testing was published in 2014. It is difficult to believe that 5 years passed… Are times still good for load testing? Well, yes and no. I am not so upbeat as I was in 2014.

Industry Trends and Performance

Alex Podelko

One software vendor ask me, along with a few other performance professionals, to answer questions related to performance trends. But they changed their mind and never published it – leaving me to contemplate which particular thought they didn’t like… Well, here are their questions and my answers: What do you think is the “next big thing in performance” – or what should we all keep an eye out for in 2018?

Reinventing Performance Testing: New Technologies

Alex Podelko

I am looking forward to share my thoughts on ‘Reinventing Performance Testing’ at the imPACt performance and capacity conference by CMG held on November 7-10, 2016 in La Jolla, CA. I decided to publish a few parts here to see if anything triggers a discussion.

The Role of Recording in Load Testing Tools

Alex Podelko

An interesting discussion started around a very good post Open Source Load Testing Tool Review by Ragnar Lönn. Somehow the latest comment, which I got in my e-mail, didn’t get published. So I decided to copy the discussion as is and publish the comment (and my answer) here. Check the original post (as well as many other great posts) following the link above – but the discussion below is somewhat independent.
