What methods would you apply for decreasing the loading time of a website?

Minimize HTTP Requests
Reduce server response time
Enable compression
Enable browser caching
Optimize images
Optimize CSS Delivery

Hi there,

There are a number of possibilities, with some degree of diminishing return:

• Caching -- often your application server will have significant latency, using a reverse proxy such as Varnish can shave off a few hundred milliseconds
  
• CDN -- offloading static assets to the edge reduces the time to serve them, especially for clients that are far away from your host
• Domain sharding -- browsers load only a certain number of assets at a given time, adding more domains (e.g. static1, static2, etc.) can increase your throughput
  
• Compression -- most browsers support gzip so your web server should compress outgoing assets, similarly you can minify CSS, JS and images
• Asynchronous JavaScript -- most script tags are blocking which means the browser won't render the DOM until all the JavaScript has been loaded -- marking some as async can improve the perceived speed
  
• Critical path CSS -- by determining which styles are used above the fold when the user first loads the page you can inline those and load others asynchronously

A lot of these can be automated by tools such as Grunt or Gulp. You can also look at Google Page Speed which can be installed on Apache or nginx.

Here are the differents methods through which you can decrease the loading speed of the website ie.
- There is some free SEO tool through which you can dec. the speed.
- Use the long length code to slow down the speed. https://magento.ocodewire.com/magento-2
