Performance issues on event servers

Summary:
The event servers seem to be poorly optimized; and even my PC, which should work fine, is struggling. Low-end devices (Switch etc.) are especially susceptible to this.

Step to Reproduce:
Just keep playing the event server (Currently available on the Eerie Mojang Office Party)

Expected Results:
The game has little to no lag spikes

Observed Results:
Sometimes the game has lag spikes, and sometime crashes

My PC specs:
CPU: Ryzen 7 5700X
GPU: NVIDIA GeForce RTX 4060 Ti
RAM: DDR4 16GB 3200MHz

For your information I have attached a video recording of a past event server on switch: https://drive.google.com/file/d/1NgmTwhP-8iTNuOfz-GAVBtKR2x_gjJwa/view?usp=drive_link
