SetPing
by apphhzp
SetPing is a Forge mod for 1.16.5 that lets server operators deliberately raise network latency and packet loss for a chosen player.
What it does
A set of commands adjusts the artificial delay and packet loss applied to network packets. Each packet can be given a random delay between a configured minimum and maximum in milliseconds, and a loss rate that drops a share of packets. The commands can target one player's client or the server side, and a player's current values can be read back.
The mod is useful for testing how a game or server behaves under poor connections, or for simulating lag on a specific player. Installation is needed on both the server and every player, since the client and server environment applies. The files target 1.16.5 only, and the mod is published for Forge, under All rights reserved, so it is not open source.
Key features
Artificial latency
Packet delay is set between a minimum and a maximum number of milliseconds, with each packet receiving a random value in that range.
Packet loss rate
A loss rate can be set so that a share of packets is dropped, separately from the delay settings.
Per-target commands
The setping commands apply to a target player's client or to the server side, and can also report the values currently in effect.
Config and debug log
A config file holds the minimum and maximum delay values, and an option enables a debug log for checking what is applied.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Testing poor connections
Developers and server staff can see how gameplay holds up when packets arrive late or go missing.
Simulating lag for one player
An operator can raise latency on a single player's client to reproduce a complaint about lag without changing anyone else's connection.
Who it’s for: Server owners and operators who need to test network conditions, and developers checking how their mods handle delayed or lost packets.
