AI-generated summary
Cloudflare (CF) is a well-known CDN provider aimed at speeding up website loading times through its global server network. However, users in China often experience slower access speeds when using Cloudflare, primarily due to two reasons: 1. **Network Latency and Routing Issues**: The connection quality between users and CF nodes can be unstable, leading to suboptimal access speeds. 2. **China's Unique Network Environment**: Interconnectivity issues among major Chinese telecom operators can create bottlenecks, affecting cross-network access speeds. To address these issues, users with servers in China might consider switching to local CDN providers like Tencent Cloud or Alibaba Cloud. For those wanting to retain Cloudflare's benefits (like free SSL and DDoS protection), optimization strategies include: - **Implementing IP Optimization**: Using an IP optimization program can help select the best path to CF nodes, improving speed. - **Combining Domestic CDNs with Cloudflare**: Users can first access a domestic CDN before routing through Cloudflare, enhancing speed while leveraging CF's features. This combined approach can improve website loading times and effectively utilize Cloudflare's security and performance enhancements.

Cloudflare (abbreviated as CF) is a globally recognized content delivery network (CDN) service provider, aimed at accelerating website loading speeds through its extensive server network. However, many users have found that using Cloudflare can actually slow down access speeds, especially when servers are deployed in China. This phenomenon can mainly be attributed to the following two reasons:

Main Reasons#

  1. Network latency and routing node issues
    Cloudflare's nodes are spread across the globe, but the connection quality between users and nodes may be unstable. If the CF node that the user connects to is not optimal, then even with Cloudflare, access speeds may be affected.

  2. China's unique network environment
    China has several major operators, such as Telecom, Unicom, and Mobile, and there are certain bottlenecks in interconnectivity between these operators, leading to limited access speeds across networks. If the routing between Cloudflare nodes and users or between users and domestic servers passes through these bottlenecks, access speeds may decline.

Solutions#

For users deploying servers domestically, the simplest method is to choose a domestic CDN service provider, such as Tencent Cloud, Alibaba Cloud, or Huawei Cloud.

However, for those who wish to take advantage of some features offered by Cloudflare (such as free SSL certificates, IP hiding, and DDoS protection), the following optimization strategies can be considered:

  • Introduce an IP optimization program
    Adding an IP optimization program between users and Cloudflare nodes can help select the best path, thereby improving access speeds.

  • Combine with domestic CDN services
    By using domestic CDN in conjunction with Cloudflare, the user access process can be optimized. The specific process is: users first access through the domestic CDN, then forward to Cloudflare, thus leveraging CF's advantages while reducing latency caused by cross-network access.

This combination method can not only enhance the website's loading speed but also effectively utilize Cloudflare's security and performance optimization features. With reasonable configuration and optimization, users can enjoy the security and performance improvements brought by Cloudflare while improving access speeds.
