Each browser instance is expensive, so use a small number alongside a larger HTTP load. Use it to measure front-end timing, not to generate volume. Here is how to use Apache JMeter’s WebDriver Sampler to load test the UI of the… Read more »

Encountering a 500 Internal Server Error can… Read more »

The GUI is for building and debugging plans, not for generating load. If you want to start Apache JMeter in non-GUI mode, use… Read more »

Compressing already-compressed images wastes CPU for nothing. Set a sensible minimum length, since compressing very small responses costs more than it saves. During Speed testing of your website or web application using LoadFocus… Read more »
