Ticks are taking 1101.6ms against a 50ms budget.

The server thread is averaging 1101.6ms per tick against a budget of 50ms. The worst tick in that window was 1282.2ms. 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 8706 entities, which is the first thing to look at.

8706 entities are sitting in one chunk at -68, 2.

world chunk -68, 2 (around x -1088, z 32) holds 8706 entities: 5655 slime, 3051 item. Every one of them is ticked, so a single chunk like this can hold the whole server back, and it is 29% of the 30386 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 -69, 2 (around x -1104, z 32) and world chunk -68, 3 (around x -1088, z 48).
