A/B testing is essential for conversion optimization, but many client-side tools come with an often-overlooked downside—performance impact. Every extra millisecond can reduce conversions, yet most platforms claim their scripts don’t slow down your site. But is that really true?

In this session, we’ll compare industry-standard A/B testing tools, break down what causes performance bottlenecks, and uncover how to minimize speed loss without sacrificing experimentation quality.

Expect a data-driven, myth-busting talk that cuts through marketing claims and gives you the insights needed to run high-impact experiments without slowing down your website.
