On my minecraft server i have 3 spawners in the corner with a distance of about 35 blocks each, the spawners are in the nether and are very, very slow man i don't know why? Perhaps it is also because these monsters do not spawn so quickly in the near future (1.Spawner: Zombies 2.Spawner: Witherskelet 3.Spawner: Hoglins (which spawns relatively quickly)) so there's a plugin or, best of all, a script with which you can can increase this, have already put everything up in the whole files from minecraft server and it still doesn't work but can there also be something that I overlooked?
You can read in the Minecraft Wiki which conditions must be met for certain mobs to spawn. Most of the time, however, they need at least 2 blocks below and 3 blocks of air above them. Cows, sheep and pigs, for example, also need blocks of grass under them.
A general command for increasing the spawn rate should be / randomtickspeed [insert number]. The default value is 3. Just set it to 100 and then the mobs should spawn much faster, provided that the tick speed affects the spawn rate.
It should all be in here: https://minecraft.fandom.com/de/wiki/Spawner
