[MC-191890] Multiple pistons activated simultaneously causes framerate drops

Powering multiple pistons simultaneously create frame rate drops compared to previous versions (i.e 1.15-1.15.2) regardless of the type of hardware the client is running on to the point of freezing the game in lower spec hardware. Multiple pistons like piston walls or large and complicated piston and slimeblock contraptions.

Please provide a short video visualizing the difference between 1.15 and 1.16, please make sure the Alt+F3 debug screen is enabled while taking the footage.

I can't really record anything on 1.16 due to it freezing to the point of crashing so I cannot put a comparison footage.

Just a screenshot with those screens enabled while it occurs is sufficient for the moment.

I updated the description linking to a youtube vid that covers the same issue.
