MainReactor completes the operation of receiving the client connection request. It is not responsible for the communication with the client, but transfers the established connection to the subReactor thread to complete the communication with the client, so that the following client connection request will not be processed immediately due to the large amount of read () data. In addition, the multi-Reactor thread mode can also distribute massive connections to multiple subReactor threads by implementing the subReactor thread pool under the condition of massive concurrent requests from clients, which can greatly improve the application load and throughput in a multi-core operating system.
