 感谢 [asio-kcp](https://github.com/libinzhangyuan/asio_kcp) 的作者 [zhangyuan](https://github.com/libinzhangyuan) 对 KCP 与 enet, udt做过的一次横向评测，结论如下：
 
 - ASIO-KCP **has good performace in wifi and phone network(3G, 4G)**.
-- Extra using 20% ~ 50% network flow for speed improvement.
 - The kcp is the **first choice for realtime pvp game**.
 - The lag is less than 1 second when network lag happen. **3 times better than enet** when lag happen.
 - The enet is a good choice if your game allow 2 second lag.
