      Description

      After MC-192845 was fixed block event lag in 1.16.2-rc1 is still excessive to the point that the client performance, compared to 1.15.2, when testing identical setups, is around 50% worse.

       

      To reproduce:

      1. In 1.15.2 setup a contraption in which pistons move a large amount of blocks, expand the system until you notice the clients frames begin to drop.

      • Observe the clients framerate 

       

       

      2. Construct the same contraption in 1.16.2-rc1

      • Observe the clients frames dropping significantly lower than in 1.15.2 

       

       

      My testing:

      In my testing I used the attached world, containing a double core 2x2 spruce tree farm designed by ilmango, which uses a large flying machine based piston wall. To activate this wall simply press the button on the back, which is shown in the screenshots.
