In SPOTREP #00058 it says under ENGINE:
Added: New #maxPing, #maxPacketLoss and #maxDesync commands for server administrators
Added: A new #disconnectTimeout command for server administrators, and maxPing, maxPacketLoss and maxDesync support in server.cfg
Added: A new kickClientsOnSlowNetwork parameter for the server.cfg (enabled by default), documentation: https://forums.bistudio.com/topic/160288-arma-3-stable-server-160-performance-binary-feedback/page-77?p=3035423#entry3035423
However, if one adds any of the above parameters into their server.cfg file the kickClientsOnSlowNetwork command will not kick any player whose connection exceeds the max[Command] thresholds nor will it output a warning message to the console or RPT log file.
