1. High concurrency
High concurrency is a state if a large number of requests are accessing the gateway interface. In this case, a large number of execution operations, such as database operations, resource requests, hardware occupancy, etc., occur. This requires optimization of the interface, and multithreading is a means of dealing with high concurrency.
2. Multithreading
It is a way of asynchronous processing, which maximizes the use of computer resources at the same time.
