Avoid slowing down the critical rendering path (avoidRenderBlocking)	The page has 1 blocking requests and 0 in body parser blocking (1 JavaScript and 0 CSS).	90
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.

Avoid CPU Long Tasks (longTasks)	The page has 1 CPU long task with the total of 253 ms. The total blocking time is 0 ms and 1 long task before first contentful paint with total time of 253 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.	80
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 extra requests by setting cache headers (cacheHeaders)	The page has 2 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 229.5 kB the next access.	80
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.

Always compress text content (compressAssets)	The page has 1 request that are served uncompressed. You could save a lot of bytes by sending them compressed instead.	90
Description: In the early days of the Internet there were browsers that didn't support compressing (gzipping) text content. They do now. Make sure you compress HTML, JSON, JavaScript, CSS and SVG. It will save bytes for the user; making the page load faster and use less bandwith.

Total JavaScript size shouldn't be too big (javascriptSize)	The total JavaScript transfer size is 228.2 kB. This is quite large.	50
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?

Avoid missing and error requests (responseOk)	The page has 3 error responses. The page has 1 response with code 401. The page has 2 responses with code 403.	70
Description: Your page should never request assets that return a 400 or 500 error. These requests are never cached. If that happens something is broken. Please fix it.

Meta description (metaDescription)	The page is missing a meta description.	0
Description: Use a page description to make the page more relevant to search engines.
Avoid unnecessary headers (unnecessaryHeaders)	There are 3 responses that sets both a max-age and expires header. There are 3 responses that sets a pragma no-cache header (that is a request header). There are 4 responses that sets a server header.	90
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.

Use a good Content-Security-Policy header to make sure you you avoid Cross Site Scripting (XSS) attacks. (contentSecurityPolicyHeader)	Set a Content-Security-Policy header to make sure you are not open for Cross Site Scripting (XSS) attacks. You can start with setting a Content-Security-Policy-Report-Only header, that will only report the violation, not stop the download.	0
Description: Content Security Policy is delivered via a HTTP response header, and defines approved sources of content that the browser may load. It can be an effective countermeasure to Cross Site Scripting (XSS) attacks and is also widely supported and usually easily deployed. https://scotthelme.co.uk/content-security-policy-an-introduction/.

Set a referrer-policy header to make sure you do not leak user information. (referrerPolicyHeader)	Set a referrer-policy header to make sure you do not leak user information.	0
Description: Referrer Policy is a new header that allows a site to control how much information the browser includes with navigations away from a document and should be set by all sites. https://scotthelme.co.uk/a-new-security-header-referrer-policy/.
