Don't scale images in the browser (avoidScalingImages)The page has 11 images that are scaled more than 100 pixels. It would be better if those images are sent so the browser don't need to scale them.0
Description: It's easy to scale images in the browser and make sure they look good in different devices, however that is bad for performance! Scaling images in the browser takes extra CPU time and will hurt performance on mobile. And the user will download extra kilobytes (sometimes megabytes) of data that could be avoided. Don't do that, make sure you create multiple version of the same image server-side and serve the appropriate one.

  • Inline CSS for faster first render (inlineCss)The page has both inline styles as well as it is requesting 14 CSS files inside of the head. Let's only inline CSS for really fast render.90
    Description: In the early days of the Internet, inlining CSS was one of the ugliest things you can do. That has changed if you want your page to start rendering fast for your user. Always inline the critical CSS when you use HTTP/1 and HTTP/2 (avoid doing CSS requests that block rendering) and lazy load and cache the rest of the CSS. It is a little more complicated when using HTTP/2. Does your server support HTTP push? Then maybe that can help. Do you have a lot of users on a slow connection and are serving large chunks of HTML? Then it could be better to use the inline technique, becasue some servers always prioritize HTML content over CSS so the user needs to download the HTML first, before the CSS is downloaded.

  • Have a fast largest contentful paint (largestContentfulPaint)Largest contentful paint is poor 4.541 s. It is in the Google Web Vitals poor range, slower than 4.5 seconds.0
    Description: Largest contentful paint is one of Google Web Vitals and reports the render time of the largest image or text block visible within the viewport, relative to when the page first started loading. To be fast according to Google, it needs to render before 2.5 seconds and results over 4 seconds is poor performance.

  • Avoid CPU Long Tasks (longTasks)The page has 12 CPU long tasks with the total of 1.381 s. The total blocking time is 781 ms . However the CPU Long Task is depending on the computer/phones actual CPU speed, so you should measure this on the same type of the device that your user is using. Use Geckoprofiler for Firefox or Chromes tracelog to debug your long tasks.0
    Description: Long CPU tasks locks the thread. To the user this is commonly visible as a "locked up" page where the browser is unable to respond to user input; this is a major source of bad user experience on the web today. However the CPU Long Task is depending on the computer/phones actual CPU speed, so you should measure this on the same type of the device that your user is using. To debug you should use the Chrome timeline log and drag/drop it into devtools or use Firefox Geckoprofiler.

  • Avoid Frontend single point of failures (spof)The page has 14 requests inside of the head that can cause a SPOF (single point of failure). Load them asynchronously or move them outside of the document head.90
    Description: A page can be stopped from loading in the browser if a single JavaScript, CSS, and in some cases a font, couldn't be fetched or is loading really slowly (the white screen of death). That is a scenario you really want to avoid. Never load 3rd-party components synchronously inside of the head tag.

  • Avoid extra requests by setting cache headers (cacheHeaders)The page has 31 requests that are missing a cache time. Configure a cache time so the browser doesn't need to download them every time. It will save 297.2 kB the next access.0
    Description: The easiest way to make your page fast is to avoid doing requests to the server. Setting a cache header on your server response will tell the browser that it doesn't need to download the asset again during the configured cache time! Always try to set a cache time if the content doesn't change for every request.

  • Long cache headers is good (cacheHeadersLong)The page has 1 request that have a shorter cache time than 30 days (but still a cache time).99
    Description: Setting a cache header is good. Setting a long cache header (at least 30 days) is even better beacause then it will stay long in the browser cache. But what do you do if that asset change? Rename it and the browser will pick up the new version.

  • Total CSS size shouldn't be too big (cssSize)The total CSS transfer size is 78 kB and uncompressed size is 408.3 kB. That is big and the CSS could most probably be smaller.50
    Description: Delivering a massive amount of CSS to the browser is not the best thing you can do, because it means more work for the browser when parsing the CSS against the HTML and that makes the rendering slower. Try to send only the CSS that is used on that page. And make sure to remove CSS rules when they aren't used anymore.

    Description: It is easy to make the favicon big but please avoid doing that, because every browser will then perform an unnecessarily large download. And make sure the cache headers are set for a long time for the favicon. It is easy to miss since it's another content type.

    Description: How many fonts do you need on a page for the user to get the message? Fonts can slow down the rendering of content, try to avoid loading too many of them because worst case it can make the text invisible until they are loaded (FOIT—flash of invisible text), best case they will flicker the text content when they arrive.

    Total page size shouldn't be too big (pageSize)The page total transfer size is 2.6 MB, which is more than the coach limit of 2 MB. That is really big and you need to make it smaller.0

    Don't use private headers on static content (privateAssets)The page has 5 requests with private headers. The main page has a private header. It could be right in some cases where the user can be logged in and served specific content. But if your asset is static it should never be private. Make sure that the assets really should be private and only used by one user. Otherwise, make it cacheable for everyone.60
    Description: If you set private headers on content, that means that the content are specific for that user. Static content should be able to be cached and used by everyone. Avoid setting the cache header to private.

  • Avoid unnecessary headers (unnecessaryHeaders)There are 8 responses that sets both a max-age and expires header. There are 4 responses that sets a pragma no-cache header (that is a request header). There are 117 responses that sets a server header. 0
    Description: Do not send headers that you don't need. We look for p3p, cache-control and max-age, pragma, server and x-frame-options headers. Have a look at Andrew Betts - Headers for Hackers talk as a guide https://www.youtube.com/watch?v=k92ZbrY815c or read https://www.fastly.com/blog/headers-we-dont-want.

    Layout shift

    The elements that have shifted place is highlighted in the image (that have a higher value than 0.01). If the element shifted outside of the viewport, you will not see it there. It can be hard to understand what content that has shifted, if that's the case, checkout the video or the filmstrip of the run.
