Plugin lagging server when logging
I just had to unload the plugin as it was lagging the server out with this command.

Calling 'OnServerCommand' on 'Logger v2.2.1' took 341ms
(Filename: C:\buildslave\unity\build\Runtime/Export/Debug/Debug.bindings.h Line: 35)

It ran the command as fast as it could untill my players notifed me something was not right then I unloaded the plugin. Which fixed the issue.
Frequent logging can cause performance issues, but ultimately the issue would need to be addressed in Oxide as the method it is using doesn't have any sort of queue or limiting, only direct to file logging.
Hi i put logger plugin and my server is lagging with 500 fps,
look at this 

Just experienced this.  Flooded the console, then kicked every player on the server for "Packet Flooding".  Unloaded and removed.

It is because it is writing every action to data file it should cache the action then write only every x time
