Since I updated my BDS to version 1.14.60 from 1.14.32, the game experience has been terrible due to the stuttering.

I tried to monitor the server while playing and found that when I'm riding a horse, running or fighting with enemies, the CPU comes to 90% or more.

When using version 1.14.32, the problem had never occurred.I didn't modified server.properties when updating.

Some key factors in my server.properties:

default-player-permission-level=visitor
default-player-permission-level=1
server-authoritative-movement=false
max-threads=8
player-idle-timeout=30
tick-distance=4
view-distance=32
