Overall Category:

The human readable speed "category"

Speed Index:

Speed Index shows how quickly the contents of a page are visibly populated. [Learn more about the Speed Index metric].

Cumulative Layout Shift (CLS):

0.01 (FAST)

The Cumulative Layout Shift (CLS) metric measures how much unexpected layout shifts affect the user experience on a page. These layout shifts occur when content moves around without prior user input. CLS

Time to First Byte (TTFB):

0.336 s (FAST)

TTFB (time to first byte) is the number of milliseconds it takes for a client’s browser to receive the first byte of the response from the web server. Usually, TTFB can be improved with faster hosting and server optimizations. TTFB

First Input Delay (FID):

3 ms (FAST)

First Input Delay (FID) measures the time from when the user interacts with your site for the first time (click a link, tap on a button, etc.) to the time when the browser is able to respond to that interaction. Google recommends keeping FID below 100ms for a good user experience. FID

First Contentful Paint (FCP):

0.72 s (FAST)

FCP (First Contentful Paint) measures the time from a user’s navigation to when the browser renders the first bit of content from the DOM. In other words, FCP marks the time at which the first text or image is painted for the user. According to PageSpeed Insights, FCP should occur in under 2 seconds. FCP

Interaction to Next Paint (INP):

34 ms (FAST)

Interaction to Next Paint (INP) is a web performance metric that measures user interface responsiveness – how quickly a website responds to user interactions like clicks or key presses. Specifically, it measures how much time elapses between a user interaction like a click or key press and the next time the user sees a visual update on the page. INP

Largest Contentful Paint (LCP):

0.851 s (FAST)

Largest Contentful Paint (LCP) is a metric that measures when the largest content in the viewport is rendered. It is used to measure how long it takes for the main content of your webpage to appear on the screen. Everything below 2.5s is considered good LCP time by PageSpeed Insights. LCP

Total Size:

910 KB

Total Size. Large network payloads cost users real money and are highly correlated with long load times.

Server Response Time:

145 ms

Initial server response time. Keep the server response time for the main document short because all other requests depend on it. [Learn more about the Time to First Byte metric](https://developer.chrome.com/docs/lighthouse/performance/time-to-first-byte/).

Final Url:

https://physics.stackexchange.com/

Canonicalized and final URL for the document, after following page redirects (if any).
