Ticks are taking 999ms against a 50ms budget.

The server thread is averaging 999ms per tick against a budget of 50ms. The worst tick in that window was 1325.2ms. A tick that runs past the budget is time the server cannot give back, and it shows up to players as rubber-banding and slow block breaking. The heaviest chunk in this profile holds 32567 entities, which is the first thing to look at.

32567 entities are sitting in one chunk at -12, 67.

world chunk -12, 67 (around x -192, z 1072) holds 32567 entities: 30748 item, 1819 snow_golem. Every one of them is ticked, so a single chunk like this can hold the whole server back, and it is 71% of the 46155 entities in the profile. Go to those coordinates and look for a mob farm without a killing layer, an item backlog on the floor, or a bred animal pen nobody culls. The next worst are world chunk -12, 66 (around x -192, z 1056) and world chunk -13, 67 (around x -208, z 1072).
