What is the best configuration for large player counts?
For 1.12.2 try using Akarin. Its a super optimised, (mostly "multicore") jar. And it even works with bukkit plugins!

The Horizon Anarchy First Impressions: It's Not Good.
" The situation with third-party software is that while additional work (from plugins) do use additional cores, the core world mechanics (ticking, etc.) largely remain the same. Attempts to make the core mechanics multithreaded include Akarin, but do be warned this is very complex work and things get buggy very easily."

Custom Events in the Blocky World: Using JFR in Minecraft

Optimising a PC for hosting a Minecraft server
Lowering your simulation distance will probably help quite a bit -- 12 is quite large. If you're running on 1.19, villagers may be a source of lag, however, I would first check with spark to see what specifically is causing lag.

1FPS after few minutes in a world.
I would take the debug piechart with a grain of salt (it's very easy for mods to get it into a messed up state where a section is opened but not closed, miscategorizing all the events that happen after it). The best profiler is spark. When you experience performance issues, do a spark profile for a minute or two

You can use something like spark to try and diagnose the issue, although I think it’s kinda complex.
