Key strategies and techniques to improve website performance

Abstract: With the rapid development of the Internet, website users have increasingly higher requirements for web page access speed. This article will introduce some key strategies and techniques to help improve website performance and improve user experience.

1. Compressed files and pictures
The size of files and pictures directly affects the loading speed of web pages. Therefore, using a compression tool to compress all files on your website is a very important strategy. Compressed files can reduce download time and improve web page loading speed. In addition, using appropriate image formats and sizes can further reduce file size and improve website performance.

2. Use caching
Caching is one of the key strategies to improve website performance. Caching the static resources of the website (such as style sheets, script files, pictures, etc.) in the user's browser can reduce the number of server requests and improve the loading speed of web pages. In addition, the use of CDN (content distribution network) can also distribute the static resources of the website to all parts of the world, closer to users and speeding up access.

3. Merge and compress files
Merging multiple CSS files and JS files into one file and compressing the file size is an effective strategy to improve website performance. Merging files reduces HTTP requests, while compressing files reduces file size, making your website load faster. At the same time, pay attention to the loading order of files, ensure that dependencies are correct, and avoid errors on the web page.

4. Optimizing database queries
Optimizing database queries is one of the important strategies to improve website performance. By using technologies such as indexing and avoiding full table scans, the query speed of the database can be accelerated and the response time of the web page can be improved. In addition, rationally designing the database structure to avoid redundant data and multiple queries can also improve website performance.

5. Compress response data
Compressing the response data of the website can reduce the file size and improve the efficiency of data transmission. The server can use compression algorithms such as Gzip or Deflate to compress the response data before sending it to the user, thereby reducing transmission time and improving website performance.

6. Reduce HTTP requests
The loading speed of web pages is related to the number of HTTP requests. Reducing HTTP requests is one of the key strategies to improve website performance. You can improve the loading speed and performance of web pages by reducing HTTP requests by merging files, using techniques such as CSS Sprites, delayed loading, and lazy loading.

7. Use asynchronous loading
Using asynchronous loading can delay the loading of certain elements of the web page, thus improving the loading speed of the web page. By placing the script file at the bottom of the page and using defer and async attributes, you can reduce the factors that affect the loading of the first screen and improve the performance of the website.

Conclusion: Through the above key strategies and techniques, the website can effectively improve performance and user experience. But it needs to be adjusted and optimized according to the specific situation. Only by constantly paying attention to and adapting to the rapidly developing Internet technology can we better improve website performance and meet user needs.
