16 minutes readKey takeaways Most API performance problems are not the API: they are authentication, data setup and rate limits. Test with realistic payloads and realistic concurrency, or the numbers describe a system you do not run. Fix the challenge that blocks releases first. The exhaustive list is less useful than the ranked one. Filtering the Signal:… Read more »
17 minutes readKey takeaways The common mistakes are testing too late, testing an unrepresentative environment, and measuring averages. Unrealistic data is the quiet one: it makes everything look faster than production. Decide pass criteria before the run, or you will interpret the result to suit the deadline. Are You Falling for These Performance Testing Mistakes? Here’s How… Read more »
16 minutes readKey takeaways Distributed generation exposed latency that a single-region test had hidden entirely. The fix came from finding which dependency dominated the tail, not the average. Re-testing after each change is what showed which one actually worked. Illustrative Scenario: Breaking Through the API Latency Barrier When Latency Starts to Hurt: A Real-World Wake-Up Call In… Read more »
13 minutes readKey takeaways AI mainly changes test design: generating realistic scenarios instead of you hand-writing them. Adaptive tests adjust load during the run, which surfaces breaking points a fixed ramp misses. It does not remove the need to decide what good looks like. Thresholds remain a human judgement. AI Reshapes Automated Load Testing: What’s Different in… Read more »
18 minutes readKey takeaways An SPA does its work after the initial HTML, so HTTP-level tests miss most of it. Test the API calls the app makes, weighted the way the app makes them. Add a small browser-level test for render timing, since the two measure different things. SPA Load Testing: Why Traditional Methods Fall Short –… Read more »
12 minutes readKey takeaways Mobile users abandon faster and on worse networks, so the tolerance is lower than desktop. Test on throttled connections rather than office wifi. Measure time to interactive, since that is when the user can actually do something. Why Performance Testing Is the Deciding Factor for Mobile-First Businesses Speed Is the Price of Admission… Read more »
19 minutes readKey takeaways Cold starts make serverless latency bimodal, so averages describe neither case. Concurrency limits and downstream throttling cap you before the function does. Test sustained and bursty load separately, because they fail in different ways. Serverless Surge: Why Performance Testing Needs a New Playbook in 2026 Serverless Adoption Has Outpaced Testing Practices In just… Read more »
