TScTCPServerOptions.ListenBacklog

 

property ListenBacklog: integer; default 5;

 

Description

Specifies the maximum number of queued connection requests that can be pending.

ListenBacklog is a socket-level property that describes the number of "pending accept" requests to be queued. If the listen backlog queue fills up, new socket requests will be rejected.

The default value is 5.

 

Note: If you expect a large number of concurrent client connections, increase the ListenBacklog value, for example: Options.ListenBacklog := 128;

Choose the appropriate value based on the project requirements and the expected load.
