Preloading resources that are loaded directly in the HTML is useless. This is because the browser reads the preload at the same time as the actual resource reference.
Preloading is useful to reduce the length of your request waterfall. Imagine the following situation:
style.css
body {
background-image: url(myimage.png);
}
index.html
<html>
<head>
<link rel="stylesheet" href="style.css" />
</head>
<body>
</body>
</html>
The process of loading the above page consists (roughly) of the following steps:
index.htmlstyle.cssbackground-image, download myimage.pngThis means your request waterfall is index.html -> style.css -> myimage.png.
By adding a preload for myimage.png the browser can download the image earlier, so your request waterfall becomes:
index.html +-> style.css
+-> myimage.png
Instead of 3, it is now only 2 requests long, which means faster load times.
Some common ways are:
But to get a better overall view of the things you can improve you can use the Chrome Audit system (Lighthouse).

See the above article link. I saw the link shared above. Preload never makes the page load the page fast. It only gives the priority to the files which is declared rel="preload" to load very early as the page loads up. You can read the article again Also the article shared by me. It will say the same.
You will need other methods to load the page fast. This method will not be helpful. There are few methods listed below you can use to make page load faster.
You can minify css and js files which will load very very fast than normal file. You can minify script and css files from (https://www.minifier.org/) here.
Avoid external links of css and js files
Avoid spaces and Newlines in code.
Use compressed images which will also load faster.
Enable Caching.
