问题：如果将网络上的所有 TCP 替换为 KCP，每个人感受到的延迟会降低吗？

The following tests are recommended:

1. Test the latency of TCP connections and KCP connections under the same network bandwidth constraints.
2. Under the same router/switch processing capabilities, use KCP/TCP to configure a large number of services at the same frequency to generate network requests, causing high network load. At this time, test the average latency under both scenarios.
