It only applies if the LCP element was a resource like an image that has to be fetched over the network. There are 3 checks this insight makes: 1. Did the resource have `fetchpriority=high` applied? 2. Was the resource discoverable in the initial document, rather than injected from a script or stylesheet? 3. The resource was not lazy loaded as this can delay the browser loading the resource. It is important that all of these checks pass to minimize the delay between the initial page load and the LCP resource being loaded. ## Detailed analysis: The Largest Contentful Paint (LCP) time for this navigation was 1,077 ms. The LCP element is an image fetched from `http://localhost:8787/lcp-discovery-delay/lcp-image.jpg`. ## LCP resource network request: http://localhost:8787/lcp-discovery-delay/lcp-image.jpg Timings: - Queued at: 1,010 ms - Request sent at: 1,011 ms - Download complete at: 1,014 ms - Main thread processing completed at: 1,017 ms Durations: - Download time: 1 ms - Main thread processing time: 3 ms - Total duration: 7 ms Initiator: http://localhost:8787/lcp-discovery-delay/index.html Redirects: no redirects Status code: 200 MIME Type: image/jpeg Protocol: http/1.1 Initial priority: Low Final priority: High Render blocking: No From a service worker: No Initiators (root request to the request that directly loaded this one): http://localhost:8787/lcp-discovery-delay/index.html Response headers - Cache-Control: public, max-age=0 - ETag: <redacted> - Connection: keep-alive - Accept-Ranges: bytes - Content-Length: <redacted> - Keep-Alive: <redacted> - Date: Tue, 18 Feb 2025 11:23:05 GMT - Last-Modified: Tue, 18 Feb 2025 11:21:06 GMT - Content-Type: image/jpeg The result of the checks for this insight are: - fetchpriority=high should be applied: FAILED - lazy load not applied: PASSED - Request is discoverable in initial document: PASSED ## Estimated savings: none ## External resources: - https://web.dev/articles/lcp - https://web.dev/articles/optimize-lcp === end content Title: PerformanceInsightFormatter Document request latency serializes the correct details Content: ## Insight Title: Document request latency ## Insight Summary: This insight checks that the first request is responded to promptly. We use the following criteria to check this: 1. Was the initial request redirected? 2. Did the server respond in 600ms or less? We want developers to aim for as close to 100ms as possible, but our threshold for this insight is 600ms. 3. Was there compression applied to the response to minimize the transfer size? ## Detailed analysis: The Largest Contentful Paint (LCP) time for this navigation was 3,604 ms. The LCP element is text and was not fetched from the network. ## Document network request: http://localhost:3000/redirect3 Timings: - Queued at: 3 ms - Request sent at: 1,529 ms - Download complete at: 3,533 ms - Main thread processing completed at: 3,538 ms Durations: - Download time: 0.1 ms - Main thread processing time: 5 ms - Total duration: 3,535 ms Redirects: #### Redirect 1: http://localhost:3000/ - Start time: 3 ms - Duration: 512 ms #### Redirect 2: http://localhost:3000/redirect1 - Start time: 515 ms - Duration: 506 ms #### Redirect 3: http://localhost:3000/redirect2 - Start time: 1,021 ms - Duration: 507 ms Status code: 200 MIME Type: text/html Protocol: http/1.1 Priority: VeryHigh Render blocking: No From a service worker: No Initiators (root request to the request that directly loaded this one): none Response headers - Transfer-Encoding: chunked - Keep-Alive: <redacted> - Date: Tue, 11 Mar 2025 10:19:12 GMT - Content-Type: text/html - Connection: keep-alive The result of the checks for this insight are: - The request was not redirected: FAILED - Server responded quickly: FAILED - Compression was applied: FAILED ## Estimated savings: FCP 3428 ms, LCP 3428 ms ## External resources: - https://web.dev/articles/optimize-ttfb === end content Title: PerformanceInsightFormatter CLS serializes the correct details Content: ## Insight Title: Layout shift culprits ## Insight Summary: Cumulative Layout Shifts (CLS) is a measure of the largest burst of layout shifts for every unexpected layout shift that occurs during the lifecycle of a page. This is a Core Web Vital and the thresholds for categorizing a score are: - Good: 0.1 or less - Needs improvement: more than 0.1 and less than or equal to 0.25 - Bad: over 0.25 ## Detailed analysis: The worst layout shift cluster was the cluster that started at 472 ms and ended at 3,343 ms, with a duration of 2,871 ms. The score for this cluster is 0.7656. Layout shifts in this cluster: ### Layout shift 1: - Start time: 472 ms - Score: 0.0003 - Potential root causes: - A font that was loaded over the network (https://fonts.gstatic.com/s/specialgothicexpandedone/v2/IurO6Zxk74-YaYk1r3HOet4g75ENmBxUmOK61tA0Iu5QmJF_.woff2). ### Layout shift 2: - Start time: 857 ms - Score: 0.0844 - Potential root causes: - An iframe (id: 8AF3A9ADB81CA7B35302D07E0B591104, url: https://www.google.com/ was injected into the page) ### Layout shift 3: - Start time: 1,352 ms - Score: 0.0068 - Potential root causes: - An unsized image (IMG) (url: http://localhost:8000/unsized-image.png). ### Layout shift 4: - Start time: 1,537 ms - Score: 0.3344 - Potential root causes: - An unsized image (IMG) (url: http://localhost:8000/unsized-image.png). ### Layout shift 5: - Start time: 2,343 ms - Score: 0.3396 - No potential root causes identified ## Estimated savings: none ## External resources: - https://wdeb.dev/articles/cls - https://web.dev/articles/optimize-cls === end content Title: PerformanceInsightFormatter INP breakdown serializes the correct details Content: ## Insight Title: INP breakdown ## Insight Summary: Interaction to Next Paint (INP) is a metric that tracks the responsiveness of the page when the user interacts with it. INP is a Core Web Vital and the thresholds for how we categorize a score are: - Good: 200 milliseconds or less. - Needs improvement: more than 200 milliseconds and 500 milliseconds or less. - Bad: over 500 milliseconds. For a given slow interaction, we can break it down into 3 phases: 1. Input delay: starts when the user initiates an interaction with the page, and ends when the event callbacks for the interaction begin to run. 2. Processing duration: the time it takes for the event callbacks to run to completion. 3. Presentation delay: the time it takes for the browser to present the next frame which contains the visual result of the interaction. The sum of these three phases is the total latency. It is important to optimize each of these phases to ensure interactions take as little time as possible. Focusing on the phase that has the largest score is a good way to start optimizing. ## Detailed analysis: The longest interaction on the page was a `click` which had a total duration of `980 ms`. The timings of each of the three phases were: 1. Input delay: 1 ms 2. Processing duration: 977 ms 3. Presentation delay: 2 ms. ## Estimated savings: none ## External resources: - https://web.dev/articles/inp - https://web.dev/explore/how-to-optimize-inp - https://web.dev/articles/optimize-long-tasks - https://web.dev/articles/avoid-large-complex-layouts-and-layout-thrashing === end content Title: PerformanceInsightFormatter ModernHTTP serializes the correct details when no requests are using legacy http Content: ## Insight Title: Modern HTTP ## Insight Summary: Modern HTTP protocols, such as HTTP/2, are more efficient than older versions like HTTP/1.1 because they allow for multiple requests and responses to be sent over a single network connection, significantly improving page load performance by reducing latency and overhead. This insight identifies requests that can be upgraded to a modern HTTP protocol. We apply a conservative approach when flagging HTTP/1.1 usage. This insight will only flag requests that meet all of the following criteria: 1. Were served over HTTP/1.1 or an earlier protocol. 2. Originate from an origin that serves at least 6 static asset requests, as the benefits of multiplexing are less significant with fewer requests. 3. Are not served from 'localhost' or coming from a third-party source, where developers have no control over the server's protocol. To pass this insight, ensure your server supports and prioritizes a modern HTTP protocol (like HTTP/2) for static assets, especially when serving a substantial number of them. ## Detailed analysis: There are no requests that were served over a legacy HTTP protocol. ## Estimated savings: none ## External resources: - https://developer.chrome.com/docs/lighthouse/best-practices/uses-http2 === end content Title: PerformanceInsightFormatter ModernHTTP serializes the correct details when requests are using legacy http Content: ## Insight Title: Modern HTTP ## Insight Summary: Modern HTTP protocols, such as HTTP/2, are more efficient than older versions like HTTP/1.1 because they allow for multiple requests and responses to be sent over a single network connection, significantly improving page load performance by reducing latency and overhead.
