Install a Horrorland - New Horror Modpack (Herobrine, Cave Dweller...) server through the Control Panel (Servers → Select your server → Game servers → Add Game Server → Horrorland - New Horror Modpack (Herobrine, Cave Dweller...))
I think this server hosting is really good. I havent experienced lag yet and the only problems ive had are regarding the mods and not the server. I would recommend this to other people as well.
