You can perform performance testing anytime, but it’s best to do it when making a significant change to the system, like updating software or adding new elements. It helps to ensure that the system works as expected and functions efficiently. Also, it flags any potential issues before they become problematic.
It’s also important to conduct performance testing when releasing a new product or service. It ensures the system can handle all the expected load and meet customers’ expectations. You should regularly test your system if you have many users, as this helps identify any potential problems quickly and prevent them from arising.
Ultimately, the best time to test is before and after any significant changes to your system. This way, you can be sure that the system performance will be up to par and meet user expectations.
