HTTP persistent connection 2 million attempt and Optimization For a server, we generally consider the QPS supported by the server.(Querypersecond ))But there is such an application, we need to focus on the number of connections that it can support, rather than QPS. Of course, QPS is also one of the performance points we need to consider. This type of application is common in message pushing systems, also known as comet applications, such as chat roo

Analysis of persistent connections and short connectionsA persistent connection means that multiple data packets can be sent continuously over a TCP connection. If no data packet is sent during TCP connection persistence, both parties need to send a detection packet to maintain this connection, generally, you need to maintain it online. A short connection is a TCP connection established when both parties ha

Liang Yinghong Introduction The TCP persistent connection service plays an important role in traditional intelligent network applications. Due to its high transmission efficiency, this service is widely used between the SCP module and the IP module of the intelligent network. For example, ss7gateway and SCF, SCF and Ines, Ines and external nodes, CN and Vn, and so on. On the contrary, TCP short connection is widely used in various web applications.
