"25 Skeleton Horses within a 50 block radius."

monsterspawn=false

Why would you allow Skeleton Horses, Traps, Zombies? No one even knows what they are, to still spawn?

You guys should know minecraft doesn't have good performance so you make an endless amount of useless entities to spawn without giving us an option to disable it. Its seriously single-handedly breaking my server.

Spawns are turned down way low for better performance, difficulty is set on high for a more challenging survival atmosphere. Now in my town around the spawn point there are seriously 25 Skeleton Horses within a 50 block radius.
