3. Never  Scale Down Your Images 

Never use a larger image than you need because width and height attributes of <img> elements can be set in HTML.

Say for Example, You need a 100x100px image but you have a 700x700px image, in this case never use the big image directly,Use of an  image editor like Photoshop is advisable in order to resize the image to the required dimensions. This will lower the file size of the image, so helps you to decrease page loading times.

4. Put Stylesheet References at the Top

Putting stylesheet references to the <head> section helps pages feel like it is loading faster.This is because it allows pages to render the styles progressively. Plus, it does not hurt that it is the W3C standard.

5. By Adding References of Script at the Bottom

At the same time, browsers can only download two components per hostname. If have added you scripts in the top,then on the initial loading of the page it would block anything else below it.User feels like the page is loading slower.

In order to avoid this, put script references as far down the HTML document as possible, preferably right before the closing <body> tag.

6. Keep CSS and Javascripts in an External Files

If your placing javascript and css directly in HTML document, they are downloaded every time when an HTML document is requested. This, increases the size of the HTML document and then, doesn’t take advantage of browser caching.

Its good practise to place your css and javascript in external files which makes the site easier to maintain and update.

7. HTTP Requests minimization

In general scenario what happen,when you visit any new web page, most of the page-loading time is spent for downloading components of that page (e.g. images, stylesheets, and scripts).

If you minimize the number of requests a web page needs to make, it will load faster. To reduce HTTP requests for images, one simple thing you can do is to use CSS sprites so that multiple images can be combined.

Multiple stylesheets and JavaScript libraries can be combined to reduce the number of HTTP requests.

8. Web Pages caching

If you using a CMS(content management system) that dynamically generates your web pages, you should cache database queries and your web pages so that the strain on your server can be decreased  and it speed up page rendering times also.

Advantage of cached page is that static version of it saved and delivered to the user instead of recreation of it every time when the request is made.

Note: Drupal core has native caching.
