Pluto

Possibly an optimised fork of Pufferfish

Features

Feature	Description
Fork of Pufferfish	Includes a bunch of performance patches.
Optimized Hoppers	Certain entities will search for hoppers allowing for a higher capacity of hoppers.
Optimisations for Farms	Certain farm related blocks can skip heavy tasks such as farmland searching for nearby water.
Optimisations for Dropped Items	Dropped items can be configured to no longer try to merge on every single tick.
Exploit Prevention	Configuration for preventing x-ray methods with certain blocks or lag machines with excessive minecarts/boats.
Full Spawner Configuration	Full configuration for mob spawners that would normally require using an API.
Tick Skipping	Whilst I don't recommend these, they unfortunately tend to be options in paid closed source forks. So now you've got access to some tick skipping methods for free.
Dev Tools Unlocker Implementation	Adds support for using the mod Dev Tools Unlocker. Note: Only enable this when you need it, clients without the mod will be unable to join.
Optimised Bukkit APIs	Some areas of the Bukkit API have been optimised to avoid plugins causing performance issues.
