We had the same problem with our old Terraria server every time we defeated or invited more friends, it either slowed down terribly or crashed altogether. The worst part was that we lost our progress in the middle of an event and couldn’t continue our adventures as we wanted. Having tried several hosts, switching to a service that is actually optimized for Terraria really helped us, one option worth checking out is https://supercraft.host/terraria-server-hosting their plans provide enough resources to handle mods, frequent player connections, and large events without constant lag. Their dashboard also simplifies backup management so you don’t lose your progress if something unexpected happens.
