Re: Avg Page Load time metrics
Average page load time means the average amount of time it takes that page to load, from initiation of the pageview to the load completion in the browser.

Secondly page load time is load time for the sample of pageviews on your site. you can see individual page speed in Behavior >> Site speed >> page timings. individual pages may have different loading time according to the content. read more about site speed https://analytics.google.com/analytics/web/#report/content-site-speed/a18735851w68469762p87922352/
