Does GA Top Posts affect my website’s page load speed?

No. GA Top Posts is built to be lightweight and fast. Analytics data is fetched from Google on the server side and cached in your WordPress database, so visitors never trigger a live API call — they always read from the cache. You control how often the cache refreshes (every 1, 2, or 6 hours) from the plugin’s configuration page. Thumbnail images are used instead of full-sized images for faster load times on the frontend.
