推荐答案

如果您使用的是Linux，答案是epoll；如果您使用的是FreeBSD或Mac OS X，答案是kqueue；如果您使用的是i/o，则答案是i/o在Windows上.

The answer is epoll if you're using Linux, kqueue if you're using FreeBSD or Mac OS X, and i/o completion ports if you're on Windows.

(几乎可以肯定)您需要研究的其他一些东西是:

Some additional things you'll (almost certainly) want to research are:

• 负载均衡技术
• 多线程网络
• 数据库体系结构
• 完美的哈希表

此外，重要是要注意的是，与TCP相比，UDP没有连接".从小规模开始并扩大规模也符合您的最大利益，因为调试基于网络的解决方案可能具有挑战性.

Additionally, it is important to note that UDP does not have "connections" as opposed to TCP. It would also be in your best interest to start small and scale larger since debugging network-based solutions can be challenging.
