Server, control method of server, and network system

Increasing the processing load on the server is suppressed in a network system in which response requests are intermittently transmitted from a client to a server. A network system has a client configured to transmit response requests at a specific time interval, and a server configured to send a response to the client according to a received response request. The server calculates a communication interval indicating an interval at which the client is to transmit its response request based on a factor affecting the processing load of the server, and sends communication interval information indicating the calculated communication interval to the client. The client transmits its response request at the time interval indicated by the communication interval information received from the server.
