21 minutes readKey Takeaways Start With a Baseline Before running any load tests, establish a clear memory usage baseline under normal operating conditions. This gives you a concrete reference point. If memory usage jumps significantly during stress tests, you can reliably spot abnormal growth and direct your investigation efficiently.

17 minutes readKey Takeaways Actionable Insights for Media Streaming Performance Simulating real-world user concurrency is essential for uncovering bottlenecks in media streaming performance. In a recent case study, a platform team preparing for a major live event ran load tests with over 600,000 simulated concurrent users. This surfaced server response delays and slow database queries – issues… Read more »
4 minutes readKey takeaways Volume testing increases the amount of DATA, not the number of users. That is what separates it from load testing. Most volume failures are queries that were fine against a small table and are not fine against a large one. Test at several data sizes rather than one. The shape of the curve… Read more »
3 minutes readKey takeaways Endurance testing and soak testing are the same thing: normal load held for a long time. It finds the failures that need hours to appear, which is why a thirty-minute load test never sees them. Compare the first hour with the last hour. Degradation over time is the entire result. The quick answer… Read more »
3 minutes readKey takeaways Spike testing applies traffic suddenly rather than ramping, which is what breaks autoscaling and cold caches. The recovery is half the test. How quickly the system returns to normal matters as much as whether it survived. Marketing sends spikes, not ramps, so this is the test that matches an email campaign or a… Read more »
20 minutes readKey takeaways Testing services individually misses the failures that appear when they call each other. Include service discovery, retries and timeouts in the test; they cause cascading failure. Trace across services or you will find the symptom rather than the source. Dispelling Myths: What Microservices Load Testing Really Requires Microservices Load Testing: Beyond Monolithic Assumptions… Read more »
17 minutes readKey takeaways Edge computing moves work closer to users, so a single-region load test no longer represents them. Generate load from multiple regions or you measure your CDN rather than your application. Cache behaviour at the edge is now part of the system under test, not an implementation detail.
