How to improve the page loading speed in website

I have to rebuild a new page with ReactJS to improve the page loading speed.

The issues which I have to solve:

Favicon - Currently loading spinner is displayed while the page is loading.
Improve the whole page loading time

It would be great if we can show the favicon while the page is loading.

Any suggestions and answers are welcome!

Solution

You can use pingdom tools to analyze your website performance.

In my case, large static files like images, audios took much time to load.

Typical Pingdom sites are like this.
