3 minutes readKey takeaways Throughput and response time diverge under load: throughput plateaus while response time climbs. The knee in that curve is your real capacity, not the maximum throughput figure. Report both. Either one alone can be made to look good. Website loading Have you ever wondered what happens when you visit a website or use… Read more »
3 minutes readKey takeaways A flaky test is worse than no test, because it trains the team to ignore red builds. Most flakiness comes from timing and shared state, not from the code under test. Quarantine and fix rather than retry. A retry hides the defect the test just found. Flaky tests are one of the most… Read more »
2 minutes readKey takeaways CPU utilisation shows whether the server is working or waiting, which changes the diagnosis. High CPU with low throughput usually means inefficient code, not insufficient hardware. Watch it on the load generator too, since a saturated generator caps the test. CPU or Central Processing Unit is the brain of any computer and its… Read more »
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 Images are usually the largest thing on a page and the easiest to fix. Modern formats and correct dimensions cut weight without visible quality loss. Set width and height so late-loading images do not shift the layout. At LoadFocus, we’ve implemented an easy way to monitor the rendering of websites on desktop and… Read more »

Monitor your top landing pages first; sitewide averages hide the pages that matter. The experience your customers get once they enter your website… Read more »
