3.3.4 Concurrent connections
JP1/DH - Server can accept concurrent connections from multiple clients for transfer. Determine the number of concurrent connections. Specifically, this includes determining the number of initial connections and the maximum number of connections. When starting up, JP1/DH - Server first reserves server resources that allow for as many connections as the number of initial connections. When the number of concurrent connections increases over time and exceeds the initial number of connections, the system dynamically assigns more server resources until the maximum number of concurrent connections is reached.
We recommend that if you know the specific average number of concurrent connections, set the initial number of connections to a value a little greater than the average.
You can set the maximum number of connections to a value based on your own environment, such as the network bandwidth. However, the upper limit for the maximum number of concurrent connections is 64. If the number of concurrent connection requests from clients exceeds the maximum number of connections, those requests are put into the connection queue (which is discussed later) and wait for a connection to become available.
