Several simple ways to improve website access speed

1. Compress the files in the website

With the widespread use of mobile devices and the increase of network bandwidth, file size can now be compressed without losing quality. This can reduce the loading time of the website. Using GZIP format compression can greatly reduce the size of HTML, CSS, JS and other files, which is very common in modern websites. Using compressed files can improve website efficiency, reduce bandwidth consumption, and load pages faster.

2. Optimize picture size and format

Images are usually one of the main reasons why websites take a long time to load. If you are using high-resolution images, consider compressing their size and format to reduce their loading time. Using appropriate image formats (such as JPEG, PNG) can also greatly reduce the size of image files, thus improving the speed of website access.

3. Accelerate websites by using content distribution networks (CDNs)

The content distribution network (CDN) can cache and distribute your website content through servers distributed around the world, so as to speed up website access. CDN enables data to reach the end user's equipment faster through multiple optical cables and nodes. CDN can reduce interaction time and alleviate network congestion.

4. Minimize HTTP requests

The number of HTTP requests has a great impact on website speed. By reducing the number of HTTP requests, you can speed up the website loading time. You can reduce the number of HTTP requests by reducing the outer chain, merging CSS and JavaScript files, and merging images into CSS Sprite images

5. Use browser cache

Frequently accessed data can be saved in the browser cache, which can speed up website access, because things that have been visited do not need to be reloaded. Almost all common Web servers support ETag or Last Modified headers, which can verify and update cached data if necessary. The cache control header can be used to implement browser caching, reduce response time and bandwidth consumption, and thus improve the website access speed.

In short, website access speed plays an important role in providing a better user experience and search engine optimization. By reducing HTTP requests, compressing file size, applying CDN and other simple methods, you can speed up website access, improve your website ranking and attract more visitors. The author suggests that website administrators should follow the principle of "simplicity, clarity, and quality first", organize the website content and architecture, reduce the number of HTTP requests, compress static resources, and maximize the website performance.
