TPS Detective

This mod helps you diagnose the issue of a "frozen world," where chunks stop generating, entities stop ticking, and blocks don't drop items.

Enter the problematic world and reproduce the problem. If the world remains stuck for more than 10 seconds, an info screen will appear.

Usually, updating or removing mods that add or modify entity or structure specified in server task label with long tick times, or mobs in list that have long tick times (>5000ms/10s) resolves the issue.

The info screen can also be opened by pressing 'O'.

For diagnosing temporary lag use Spark mod.

Rn the mod only works for world hosts and does nothing on dedicated servers.
