sync tile entity seems to be hitting hard on tickloop. If you need any more information I'll do my best to help.

Thank you.

well... I can't see that screenshot... :(... or whatever that is..

It's a very popular screenshot sharing application.

Same issue here, the only mod I have which uses teslacorelib is industrial foregoing.

Also here are the top packs which get send:

can you say what tile entities are you using from IF?... or are you using many of them?

It's on a server with a lot of players, so pretty much all of them.

what version of TCL is this?... also do you have any idea what tile entity is doing this?

I wonder why it needs to sync the machines on every update and not only when the player opens it.

same here... as far as I remember the latest TCL (also a series of prior versions) should have this fixed and updates should only happen if a GUI is opened... unless otherwise specified.

I promise to make time soon to look at this :)

changed the defaults... should be a lot better now...

can one of you please test against the maven version: https://maven.mcmoddev.com/net/ndrei/tesla-core-lib/1.12.2-1.0.15.12/
