Inventory Access Port and Bridge issue

[ZZofa]

Minecraft 1.20.1-forge 47.4.2
Create 6.0.6, Connected 1.1.5

If I place 4 access port or bridge together in a 2*2 square, it causes extremely lag.
Ticks goes extremely slow, causes glitches like sand cannot fall immediately in air.

I can provide videos, logs and mod lists if need.
