The best thing about performance testing is that it allows you to test everything from speed of page load time to responsiveness across different browsers and devices. It's also easy to use with no coding required! I dislike how slow some tests take so it can be frustrating especially if they are not very specific or detailed in their instructions. If you're looking for an all-inclusive solution that will help you optimize every aspect of your website then this tool is perfect for you. We tested our mobile app which included loading pages as well as user experience (UX).
