The difference between performance testing and performance tuning

Whether you’re new to DevOps or an experienced hand, sometimes it’s a challenge to explain the difference between performance testing and performance tuning. It happens to us, too. Here’s how we describe understanding performance testing and performance tuning.

Advanced Load Testing: When to Use Simulated User Data in Load Tests

For the most accurate load test, best practices (and common sense) dictate that your testing environment be as close to real production and user behavior as possible. We get it, though! Best practices don’t necessarily reflect the challenge and rush of a real development pipeline. For example, if you’re like us, you likely have a much larger amount of data in your production environment than in your testing and staging environment. A detailed, extremely realistic testing database is nice, but perhaps not necessary. Let us explain.

Three Load Tests You Must Run

The concept of load testing seems simple. You just run a test against your app, API or site and see how it performs under a simulated user load. But the reality is slightly more complex. There are three load tests you must run to optimize performance.

Understanding Performance Logs for Performance Tuning

We believe load tests are your performance guardians. If the minimum performance levels you’ve set aren’t met, a build should fail. Load testing is as important as unit and functional testing, and we run our load tests with every nightly build. No matter how small our code changes are, we use load tests as safety mechanisms to make sure we didn’t accidentally torpedo our performance with a small change. (Nowadays systems, apps and dependencies can be so complex it’s difficult to predict how any change will affect the rest of the system.)
