I use SpeedVitals daily to understand what is holding a WordPress site back and how to meet Core Web Vitals metric thresholds. Their TTFB test tool is one of my favorites!

Importance of Website Speed

24% Less
A Google study over millions of page impressions found that when a site meets the recommended thresholds for the Core Web Vitals metrics, users are at least 24% less likely to abandon a page before it finishes loading.
Bing observed that an engineer that improves server performance by 10ms (that's 1/30 of the speed that our eyes blink) more than pays for his fully-loaded annual costs. Every millisecond counts.
