The Kernl WP Site Performance Monitor tracks your WordPress site performance all from the comfort of your own WordPress Admin. Easily keep track of: Response time – We will check your site’s response time every 10 minutes and graph it out over the past 24 hours. Time to first byte (TTFB) – In addition to response time, we track TTFB so you know how quickly your site responds initially to requests. Lighthouse Scores – The same tool that powers Google’s PageSpeed Insights is automatically run against your site once a day.
