Avoid slowing down the critical rendering path (avoidRenderBlocking)The page has 2 blocking requests and 0 in body parser blocking (0 JavaScript and 2 CSS). There are 1 potentially render blocking requests. You need to verify if it is render blocking: https://en.m.wikipedia.beta.wmflabs.org/w/load.php?lang=en&modules=startup&only=scripts&raw=1&skin=minerva99
Description: The critical rendering path is what the browser needs to do to start rendering the page. Every file requested inside of the head element will postpone the rendering of the page, because the browser need to do the request. Avoid loading JavaScript synchronously inside of the head (you should not need JavaScript to render the page), request files from the same domain as the main document (to avoid DNS lookups) and inline CSS for really fast rendering and a short rendering path.
Offenders:
  • https://en.m.wikipedia.beta.wmflabs.org/w/load.php...bs.org/w/load.php
  • Inline CSS for faster first render (inlineCss)The page has both inline CSS and CSS requests even though it uses a HTTP/2-ish connection. If you have many users on slow connections, it can be better to only inline the CSS. Run your own tests and check the waterfall graph to see what happens.95
    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.
    Avoid CPU Long Tasks (longTasks)The page has 14 CPU long tasks with the total of 2.782 s. The total blocking time is 1.987 s and 1 long task before first contentful paint with total time of 145 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 doing redirects (assetsRedirects)The page has 3 redirects. 1 of the redirects are from the base domain, please fix them! 2 requests are from other domains, it could be 3rd-party assets doing unnecessary redirects. :(70
    Description: A redirect is one extra step for the user to download the asset. Avoid that if you want to be fast. Redirects are even more of a showstopper on mobile.

  • Avoid extra requests by setting cache headers (cacheHeaders)The page has 11 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 68.4 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 4 requests that have a shorter cache time than 30 days (but still a cache time).96
    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 JavaScript size shouldn't be too big (javascriptSize)The total JavaScript transfer size is 308 kB and the uncompressed size is 1.3 MB. This is totally crazy! There is really room for improvement here. 0
    Description: A lot of JavaScript often means you are downloading more than you need. How complex is the page and what can the user do on the page? Do you use multiple JavaScript frameworks?

    Don't use private headers on static content (privateAssets)The page has 2 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.90
    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 too many third party requests (thirdParty)The page do 19% requests to third party domains (6 requests and 66 kB). First party is 25 requests and 535.7 kB. The regex .*wmflabs.* was used to calculate first/third party requests.50
    Description: Do not load most of your content from third party URLs.
    Avoid unnecessary headers (unnecessaryHeaders)There are 19 responses that sets both a max-age and expires header. There are 31 responses that sets a server header. 50
    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.

    These HTML elements contribute most to the Cumulative Layout Shifts of the page. The higher score, the more layout shift.
