Stop Guessing and Start Measuring - Benchmarking in Practice

this Topic will be presented by Tobias Pfeiffer

at August Meetup 2017, hosted by Tobias Pfeiffer

“What’s the fastest way of doing this?” – you might ask yourself during development. Sure, you can guess what’s fastest or how long something will take, but do you know? How long does it take to sort a list of 1 Million elements? Are tail-recursive functions always the fastest?

Benchmarking is here to answer these questions. However, there are many pitfalls around setting up a good benchmark and interpreting the results. This talk will guide you through, introduce best practices and show you some surprising benchmarking results along the way.
