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.

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 4 CPU long tasks with the total of 682 ms. The total blocking time is 0 ms and 4 long tasks before first contentful paint with total time of 682 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.

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 8 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.

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 20 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 492 kB the next access.

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.

Total CSS size shouldn't be too big (cssSize)

The total CSS transfer size is 117.6 kB and uncompressed size is 815.6 kB. That is big and the CSS could most probably be smaller.

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.

The favicon should be small and cacheable (favicon)

The favicon has no cache time.

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.

Avoid too many fonts (fewFonts)

The page has 4 font requests. Do you really need them? What value does the fonts give the user?

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 image size shouldn't be too big (imageSize)

The page total image size is 1.7 MB. It's really big. Is the page using the right format for the images? Can they be lazy loaded? Are they compressed as good as they can be? Make them smaller by using https://imageoptim.com/.

Description: Avoid having too many large images on the page. The images will not affect the first paint of the page, but it will eat bandwidth for the user.

Total JavaScript size shouldn't be too big (javascriptSize)

The total JavaScript transfer size is 978.2 kB and the uncompressed size is 2.4 MB. This is totally crazy! There is really room for improvement here.

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?

Make each CSS response small (optimalCssSize)

https://static-catalog.diamant.ru/_next/static/css/d952859c721b8e52.css size is 70.3 kB (70327) and that is bigger than the limit of 14.5 kB. https://static-catalog.diamant.ru/_next/static/css/13226014bc357e4b.css size is 20.1 kB (20122) and that is bigger than the limit of 14.5 kB. Try to make the CSS files fit into 14.5 KB.

Description: Make CSS responses small to fit into the magic number TCP window size of 14.5 KB. The browser can then download the CSS faster and that will make the page start rendering earlier.

Total page size shouldn't be too big (pageSize)

The page total transfer size is 3.1 MB, which is more than the coach limit of 2 MB. That is really big and you need to make it smaller.

Description: Avoid having pages that have a transfer size over the wire of more than 2 MB (desktop) and 1 MB (mobile) because that is really big and will hurt performance and will make the page expensive for the user if she/he pays for the bandwidth.

Avoid too many third party requests (thirdParty)	The page do 24% requests to third party domains (21 requests and 1.4 MB). First party is 65 requests and 1.6 MB. The regex .diamant. 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 16 responses that sets both a max-age and expires header. There are 2 responses that sets a pragma no-cache header (that is a request header). There are 86 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.

The Largest Contentful Paint API highlighted this image as a part of the LCP.

Detected Cumulative Layout Shift

0.00005 cumulative layout shift collected from the Cumulative Layout Shift API.

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

Score	HTML Element
0.00005	<span class="CitySelectButton_city-text___XqH_"></span>,<button class="ButtonDeprecated_sklv-button__Wy8xr ButtonDeprecated_sklv-button_borderless__776ey" types="borderless"></button>

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.
