Pixelmon Server Can't keep up! Did the system time change, or is the server overloaded?

When the server is lag, the console will display such a message [Server] Server thread/WARN Can’t keep up! Did the system time change, or is the server overloaded? Running 2024ms behind, skipping 40 tick(s)

Quite serious, sometimes even lags 10 seconds, I really need to solve this problem, I also did according to Rasgnarok’s Docs, but this is still happening

This is the configuration of my sponge: https://pastebin.com/2zGiJute

What are your server specs? Honestly (and I may be wrong, I did just wake up), it looks like there are just way to many entities for your server to handle.

I only know that the memory is 32GB, this is a rented server https://theminecrafthosting.com

Can you please contact me directly at @Rasgnarok#6969 in https://pixelmonmod.com/discord, it’ll be far more simpler. I tried getting in contact with you there, but it would be simpler if you send me your updated debug.log directly to my DMs, thanks!
