7 minutes readKey takeaways Response time alone hides the problem. Track throughput, error rate and resource use alongside it. Percentiles tell you what users actually experience; averages hide the slow tail. Decide which metrics matter before the test runs, or you will rationalise whatever the run produced. During crucial performance testing session we need to monitor and… Read more »
2 minutes readPerformance testing is a generic term that refers to testing how an application behaves under load. Performance testing should be done continuously not just on specific milestones, as this brings benefits related to: how the performance improves/degrades during the releases can be a very early indicator that something has gone wrong that might really affect… Read more »
3 minutes readKey takeaways Users judge speed in the first couple of seconds, and most sites lose them there. Slowness is usually a handful of large assets rather than a systemic problem. Measure before assuming; the obvious culprit is often not the cause. Have you ever entered a website and realized how slow things move, you just… Read more »
3 minutes readKey takeaways Notes capture why a run looked the way it did, which raw metrics never record. Write the note at the time. The context is gone within a week. They make historical comparison useful, since you know what changed between runs. We’ve added the functionality to add notes to your load test results. This… Read more »
4 minutes readKey takeaways Setting a baseline turns each run into a regression check instead of a standalone number. Update the baseline deliberately when performance genuinely improves. Compare full results, not just the summary, since averages hide a worse tail. The load test comparison feature build-in to LoadFocus Results allows you to compare the results of two… Read more »
4 minutes readKey takeaways A CSV data set gives each virtual user different inputs, which is what makes a test realistic. Set sharing mode deliberately: all threads, per group or per thread produce different tests. Decide the recycle behaviour, or threads silently reuse the same rows. Apache JMeter is a Java-based, open source testing tool, which can… Read more »
5 minutes readKey takeaways An average hides the slow tail, and the tail is what users complain about. p95 and p99 describe the experience of your least fortunate users. Report a percentile with the median; the mean alone can hide a serious problem. Why Performance Testing We all want our websites to be responsive and useful. However,… Read more »
