Netty entry thread model

Single-threaded model: the boss thread is responsible for connection and data reading and writing

Hybrid model: the boss thread is responsible for connection and data reading and writing, and the worker thread is only responsible for data reading and writing

Master-slave model: boss thread is only responsible for connection, worker thread is only responsible for data reading and writing

If the number of connections is 10w, even using epoll is very slow, so more data is needed for fragmentation. Assuming that 10w fds are divided into 100 parts, each part corresponds to one epoll_wait(), then a single multiplexer is dispersed pressure. All these functions can be configured in netty, the code has already been written by others, you only need to use it
