Heavy comparison tables can seriously slow down your page because they require extensive browser processing to render. When your browser encounters a large table, it must parse complex HTML structures, calculate CSS layouts, execute JavaScript for interactive features, and perform multiple reflow operations. This affects Core Web Vitals metrics like Largest Contentful Paint (LCP) and Time to Interactive (TTI), directly impacting both user experience and search rankings. For trading affiliate sites with broker comparisons, understanding and addressing these performance issues is essential.
