I want to ask an additional question. Does Growthbook's a/b testing feature affect page performance (Page speed etc.)?

Our SDK and its internal evaluation logic are lightweight and very performant. However, it really depends on how you use us. Backend tests will be the fastest. Frontend-only tests which modify the DOM can be done efficiently but more care is needed during implementation to not negatively impact your CWV (core web vitals) stats.
