Pehkui 1.14-1.17.1 lagging and most recent version causing connection lost error

  • So I'm using this server me with my friends with Fabric, 1.16.5 and we're using the Pehkui mod (version listed above) however its causing this extreme lag whenever we have it on and it causes a crash every now and them from the client side. The move recent version just causes the server unable to be joined with a "connection lost error" Is there any way to fix this? or maybe a version of Pehkui that has the /persist command in it that doesn't cause this much lag.
