In 1.19.2 when an angel appears and moves, it starts to slow down the server, either a single player or a lan, there are peaks of 300 ms when the angel moves.

Same issue here. I'm using forge 43.2.14, with Weeping Angels v43.0.9. The lag is so bad when they are trying to move/teleport, I had to manually disable their spawns because players found it so frustrating to play against.

Here is a link to a spark profiler.

Are you sure you linked the correct spark report? The entity count summary doesn't list angels

Pretty sure that's the correct one. I was looking through the server thread and went to ServerLevel.tick() --> guardEntityTick() --> OnTickNonPassenger() --> WeepingAngel.tick() --> Teleporter.performTeleport(). Weird that it doesn't show up in the entity count summary but yeah.

During the lag spike, there was only 1-2 Weeping Angels as well, not like 10+.

Perhaps I’m just unfamiliar with sparks ui these days

There does seem to be a bug where Angels are teleporting each other and other random entities which would definitely cause a lag spike - I will write something to rectify this and upload a jar to this issue and see if it fixes your lag?

Sure, thank you!

I also noticed that in the version prior to the latest version in 1.19.2 they do not spawn directly, but the lag still exists.

Also note, that unlike the companion I tested it with all versions of forge 43.x.xx

Fixed for 1.20, I will backport soon
