It might be worth looking into Tuinity, it's a fork of Paper with a bunch of extra performance features.
https://github.com/Spottedleaf/Tuinity

I didn't test anything but for someone more involved it appears to include:

• A port of Starlight, a complete lighting engine rewrite that's much faster than vanilla/paper/phosphor (fabric optimization mod)
  https://github.com/Spottedleaf/Starlight
• Rewrite of chunk loading for players, could potentially fix portal lag?
• Other patches relating to villager AI and general POI

Great idea

If Mojang just implements the damn aether engine into their game we wouldn't need any plugins at all lol.
