How third-party categories affect the four LCP phases
Across the four LCP sub-parts in Chrome's field data, the largest gap between framework and bot detection sits in resource load delay: 446 ms median for framework against 569 ms for bot detection. Overall median field LCP is 1.1s for framework (TTFB 404 ms, load delay 446 ms, load duration 110 ms, render delay 150 ms) versus 1.4s for bot detection.

Third-party technology categories or the framework
Does the framework explain the third-party technology categories difference?
Almost every site with RUM third-party technology categories is a React site, and almost every React site has RUM third-party technology categories, so the data can't tell RUM third-party technology categories and React apart.
Almost every site with framework third-party technology categories is a React site, and almost every React site has framework third-party technology categories, so the data can't tell framework third-party technology categories and React apart.
On React, 97% of sites with bot detection third-party technology categories have a good INP, against 96% of React sites with RUM. Within React, sites with bot detection and RUM have a good INP about equally often.
On React, 98% of sites with A/B testing third-party technology categories have a good CLS, against 97% of React sites with RUM. Within React, sites with A/B testing and RUM have a good CLS about equally often.
