So far this year, all but one of my clients have been concerned about Google’s upcoming Web Vitals update. The client who’s bucking the trend is great, not least because it’s given me something a little different to focus on—they’re more interested in how their site fares on iOS. What makes this particularly fun for me is that iOS Safari is a completely different ballgame to Chrome, and not something many people tend to focus on.

Today, every business wants high-performing and high-quality software. But usually, it is seen that most of the applications fail to deliver expected performance under peak load or fluctuating network conditions. To ensure that users get high-performing software that works seamlessly under all load conditions, performance testing is necessary. This test helps to measure the speed, scalability, reliability, and stability of software under varying loads, thus it ensures stable performance.

On the contrary, it is almost always because they have developed better and more modern ways to solve those same problems. But habits are hard to break; ask me how I know. All too often, I see people clinging to an older way of accomplishing some task, even though a better way exists.
