The /cping command displays the network latency (ping) of yourself or another player on the server.

/cping [<player>]

• Checking Your Own Ping: /cping
• Checking Another Player's Ping: /cping <player>

• Ping, or latency, is the time it takes for data to travel between your computer and the server.
• A lower ping indicates a better connection, while a higher ping can cause lag.
• The command displays the latency as reported by the client. It is possible for this value to be inaccurate.
