Optimizing Help with spawners

Heyo! I'm having a lot of lag with spawners, i've tried using the recommend paper-world.yml/spigot.yml/bukkit.yml etc. They haven't really helped as much, mobs once they're out of spawners don't get stacked so there are a bit of them even after using Wildstacker etc. Would anyone know a plugin or specific setting in paper-world.yml that i can just set higher, to stack mobs? I am using wildstacker so it might be unsupported?
