SetPing
An interesting mod that can deliberately increase network latency.
About this Mod
English
This mod adds a command /setping that can deliberately increase latency and packet loss rate for game network packets.
In the config file, you can adjust the minimum and maximum packet delay values, as well as enable debug log output.
Command Format
/setping get [<player>]
Requires Level 2 permission. This command is used to obtain the latency and packet loss rate settings for the target player on both the client and server sides.
/setping client <rate> <min_ping> <max_ping> [<player>]
Level 3 permissions are required (if a target player needs to be specified, level 4 permissions are required). This command is used to set the packet delay and packet loss rate from the target player's client to the server.
Among them, rate is the packet loss rate, and the packet delay will be a random number (in milliseconds) from min_ping to max_ping, the same applies below.
/setping server <rate> <min_ping> <max_ping> [<player>]
Level 3 permissions are required (if a target player needs to be specified, level 4 permissions are required). This command is used to set the packet delay and packet loss rate from the server to the target player's client.
中文
这个模组添加了一条命令/setping，可以手动给游戏的网络发包增加延迟和丢包率。
在config文件中可以调整发包延迟的最小值和最大值，以及开启debug日志输出。
命令格式
/setping get [<player>]
需要2级权限，用于得到目标玩家在客户端与服务端上的延迟和丢包率设置。
/setping client <rate> <min_ping> <max_ping> [<player>]
需要3级权限（如需指定目标玩家，则需4级权限），用于设置目标玩家的客户端向服务端的发包延迟和丢包率。
其中rate为丢包率，发包延迟将为min_ping到max_ping中的随机数（单位为毫秒），下同。
/setping server <rate> <min_ping> <max_ping> [<player>]
需要3级权限（如需指定目标玩家，则需4级权限），用于设置目标玩家的服务端向客户端的发包延迟和丢包率。

SetPing server crashes on startup – what to do?
Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.16.5). You can switch loaders with one click in the panel.
Is SetPing compatible with forge?
SetPing officially supports forge for Minecraft 1.16.5. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with SetPing – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if SetPing consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
