This is an unofficial continuation of the mod found here.
Opis is a server profiler for Forge server.
It provides a set of commands to get timing for entities and tile entities. Once the server is profiled, it will display the results in a nice list and allow you to teleport directly to the source of lag to check it out.
It comes packed with MapWriter to support the display of the locations and quick teleportation.
This version is only an alpha. There will be crashes. Please report them.
