How to improve the opening speed of the website?

If you are a website user, you can speed up the opening of web pages by upgrading broadband, fiber optics, upgrading CPU memory, optimizing the operating system, and so on.

If you are a website builder, you can improve your access speed in the following ways:

1. Optimize the code. Delete redundant code, such as useless spaces, newline characters, comments, JS that does not need to be loaded, etc.; merge JS code with CSS style to reduce the number of requests and improve the loading speed of web pages

two。 Reduce unnecessary elements on the page. Browsing the web is actually downloading the contents of the virtual host to your local hard drive and viewing it using a browser. Therefore, the smaller the space taken up by the web page itself, the faster the web browsing speed will be. Try not to use flash animation, a large number of pictures, or multimedia resources (such as video, audio, etc.).

3. Try to use static pages. Static pages run directly on the client, without server editing, can be directly displayed on the browser, and the access speed is relatively fast. Although the dynamic page is interactive, this kind of program needs to be processed by the server to generate the HTML page, and then browse through the browser, the display speed of the web page is slow.

4. Simplify the page structure. When designing a web page, many webmasters, in order to pursue the alignment of the page, put the whole page content into a Table, and then divide each block by the cell, which will slow down the display speed of the web page. Because Table needs to wait for all the content to be loaded and then graded and displayed, if some content is difficult to load, the whole page will not be displayed. The right thing to do is to use the page structure of DIV+CSS, which enables the page to be loaded step by step.

5. Use CDN to accelerate the network. CDN is the content distribution network, which can redirect the user's request to the nearest service node according to the network traffic and the link of each node, load status, user's distance and response time and other information in real time. This allows users to get the content they need nearby and improve the response speed of the web page.

6. The larger image uses lazy loading (Lazy Load). Picture lazy loading, also known as picture delay loading, lazy loading, that is, loading when users need to use pictures, which can reduce requests, reduce server pressure, and improve page loading speed.

7. Compress the picture before using it.
