test methodologies Questions

Hi there, I'm a digital and social media marketer. My career has felt limited recently and I'm considering having a new direction. I need some guidance and ask a few questions about if it makes sense for my case. Is anyone willing to reply my questions. Your support means a lot.

Many thanks, Zehra

Can anyone introduce a performance testing tool that you feel good about. I am currently using this called PerfDog. It includes a deep analysis mode, offering in-depth insights into CPU scheduling, usage, thread running states, call stacks, and rendering screenshots. It allows me to pinpoint performance issues at the function or module level, enabling timely optimization and repairs. Additionally, PerfDog embraces collaboration with a web data management platform, facilitating multiple human collaboration analyses for comprehensive performance evaluation. I think its pretty good but I am also looking for something better, has anyone get the same experience as me? Or can you recommend me some other tools?

can i get a small help about selenium and scrolling the left panel only?
