About cave & clift's incomplete feature

The frequency of opening BDS servers is now increasing, and the platform's feature level has also improved. But has a problem with the active feature or of Cave & Clift that is LAG. In the process of purging the version memory bug before claiming it was fixed, I am very grateful to the publisher who fixed it from ticket BDS-14781 that I requested to be fixed. So this time I opened the ticket for Mojang publisher to fix the Cave & Clift feature. Specifically the error when I restarted the server but this time turned on the Cave & Clift feature and installed it, after many tries and discovered the lag error from Cave & Clift, nothing else failed. memory as ticket BDS-14781 which I updated the topic with above. Every time when opening a Server with only 15 people or more, the server started showing a LAG (delay) sign, things became difficult to switch and that affected even eating a natural item or fighting a living creature any thing that. This I tried immediately with the new map. After I opened a new map without Cave & Clift, miraculously, in my server over 30 players also no lag or lag issues. I will send pictures of my computer and network configuration, hope to receive a good response from Mojang as well as the game manufacturer to fix this problem as soon as possible until version 1.18 is officially released.
