What is the loading speed?

Page load speed is the average time it takes for a page to appear on the screen.

It is calculated from startup (when a page link is clicked or a web address is typed in) to completion (when the page is fully loaded in the browser).

Usually measured in seconds, the page loading time is made up of two different parts:

Network and server time: based on how fast the Internet connection is and how quickly static assets, such as photos and other files, are served.

Browser time: how long it takes for the browser to analyze and execute the document and process the page so that it is available for user interaction.

The same web page may have different page load times in different browsers (e.g., Safari vs. Internet Explorer), on different platforms (e.g., mobile vs. desktop), and in different locations.

If your site is completed by a data center in the United States but sells to customers in Australia and the United Kingdom, for example, international buyers are likely to experience much longer load times.

But if your site’s static assets are copied to different data centers around the world, the page will be extracted from the data center closest to where your buyers are.

This can dramatically speed up page load times.

Different pages on the same site can also have radically different loading speeds, due to developer decisions such as richer design elements, more robust functionality and more content on a page.

There are several tools online to determine average page load times, which means that the web development team can focus on optimizing the slowest loading pages first.

The loading speed of a web page in the browser will depend on many factors, here we refer to some basic elements as follows:

The location of your server

If the location of the server is closer to people, they will access it more quickly.

Because if the server is in other countries, the connection has to go through many different open networks, so they have to consume more time to access it.

The ability to process server access requests

When you visit a page of the website, the browser will send a request for access to the web server, the web server will accept and classify and send the requirements to other applications, if necessary, such as PHP, MySQL, Ruby, etc.

These applications will calculate and return the results to the web server, which will respond to this result to the browser, and then the browser will process and display the response data.

Therefore, if your separator is good with the high-speed Internet connection but was not configured correctly, it will be slower with time and ability to handle errors and will make people wait longer before they can access it.

In this situation, try to optimize the code within the site and limit errors to a minimum.

For the server, you can use other techniques to increase the speed of data processing on the server such as caching for the website, optimized PHP code processing capabilities (you can use APC, XCache).

Size of website data

If your site has too many images that will increase the size of the content to tens of megabytes, it will probably have long load times, even if you have a good server.

At that point, the loading speed will depend on the quality of the access network. If the network is fast, it will load 10MB in an instant, but it is a problem if the network is resilient.

Therefore, you should avoid using large image sizes as much as possible and combine the steps to optimize the images as the right way to use them on your website.

Data buffering in the browser

Modern browsers today have the ability to store website content in your computer’s cache for reuse if you need to access the website again.

This method will help the browser display the website faster because it does not have extra time to reload the content from the web server.

For example, the browser can store all the content of the website or save the attachments, such as CSS, JavaScript, images, flash, etc.
