How do you reduce page load time?
Reduce external resources.
compress CSS, minify your JS, compress images (use tech like gulp). it's good practice to put all styles in one file and compress it. that way the server loads the CSS once. and browsers nowadays cache everything so, that helps, mostly
with using AJAX framework. It allows you to update only the form you need, not the whole page.
Use Accelerated Mobile pages, optimize and compress/minify your files and images. For faster loads, you can also use a CDN such as Cloudflare or Amazon Web Services. Also place the <script> tag at the end of the page so that scripts keep loading and don't interfere with the loading of the page
Too much Images and videos are the main cause of increased page load time, to check this you need to minimise the amount of media files contained in your page
Most OS's have a limit setting for simultaneous connections you can make to a server. It's a client setting. Other than this all the obvious things that affect bit-rate and parallel operations apply: you need (server and client) less data, more bandwidth, more threads, a faster computer, less contention, simpler layout, fewer uncached dependencies, a simpler protocol, etc. Quite a lot of work also exists to make DOMs "finish" faster. Some continue in the background (AJAX, QUIC, ...) or... Libraries are almost permanently cached. Just use a global source, so the only thing that happens is: "Did <library> change? No? I'll use my local copy then." Linked versions *never* change, hence the browser command from Google to 'cache for 1 year'. SoloLearn might flush their cache, but that would be a 'safe default' accommodation for beginners.
(imagine in-code optimization) A post reminded me...to skip one round-trip to the server, append the first slash - also after any 'folder' (otherwise the browser requests which folder to start on...which for most sites is root: /) https://www.google.com 2 trips https://www.google.com/ 1 trip Specifying https:// when you know you want it: skips protocol discovery (the visit to http: port 80, then 30x redirect -- or worse, meta/page redirects -- to https: port 443) DNS misconfiguration can also really mess up performance. If you intend to configure DNS, practice, learn, get it right.
with Ajax, which permit you to reload only the updated part
Google PageSpeed Insights API* will give you automatic suggestions: https://developers.google.com/apis-explorer/#s/pagespeedonline/v2/ * "Analyzes the performance of a web page and provides tailored suggestions to make that page faster."
adding CSS before d ending of <head > and stript before the ending of
Reduce the amount of large items and files
compress css, clean all codes but most important compress your images and reduce the external sources at minimum, use svg instead pngs or jpgs. always less is more!
Optimize your js and css files! Delete unneeded files from loading web page
Try to keep the code optimized. Use optimized images. Avoid unnecessary codes and variables. Look at the Google page source they didn't even write the code in extra spacing to reduce the page load time. If you are using images first of all make them web usages in Photoshop to get the least size.
Link your scripts externally and place them just before the closing body tag. This reduces delays in waiting for pages to render
Delete unused code, minimize (compess) your code and use inline styles in head tag of your html files! my pages have all a 100/100 scoring :-)
