NeoPerformance

FEATURES:

• Prevent server lag by preventing many forms of lag machines and optimizing standard gameplay.
• Prevent server crashes by halting the server at set TPS.
• SmartClear – Remove large clusters of entities, this is better than the standard entity removal method that most lag prevention plugins use.
• Chunks – This shows the top chunks that have the most entities.
• SmartNotify – Notifies admins when there are too many entities that are causing lag.
• Send emails when the server is lagging.
• Highly customizable (Check YML file at the bottom of the page)

COMMANDS AND PERMISSIONS:

• /Neoperformance or /np (neoperformance.admin) – Shows server status for admins
• /np help (neoperformance.help) – Shows all the commands their use
• /np halt (neoperformance.halt) – Manually halt the server
• /np chunks <world> (neoperformance.chunks) – Show the chunks with the most entities. Type /np chunks to show the top 10 for all worlds and /np chunks <world> for the top ten of the specified world.
• /np reload (neoperformance.reload) – Reload the plugins config file
• /np bypass <player> (neoperformance.bypass) – Bypass server halt
• /np smartclear <flags> <neoperformance.smartclear> Destroy entity clusters
• For SmartNotify, an integrated notify system with chunks and clusters, either have op or neoperformance.smartnotify

LAG PREVENTION:

• Prevents too many explosions
• Prevents too many mob spawns
• Prevents lag machines, such as too many minecarts.

CRASH PREVENTION:
If the plugin fails to prevent lag, the server will enable halt mode and stop the following activities until the server was reached a stable tps:

• Teleportation
• Players moving too fast (speed hacks, etc)
• Entity explosions
• Redstone (Redstone activity is cached and then restored once the server reaches a stable tps, meaning redstone contraptions won’t break)
• Chunk loading
• Entity spawn events (and items from being dropped)
• Command blocks executing commands
• Block being broken (because items can’t be dropped)
• Projectiles
• Entity breeding
• Entity targetting
• Block physics
• Players from joining (extreme lag can be caused by too many players, the plugin stops players from joining until the server is at a playable state)
