This product contains three highly optimized files that are sure to change the way your server works for the better. This is not a plugin or script nor does it require you to do anything but just click install and that's it.
What will happen is that your bukkit.yml, spigot.yml and paper.yml will be replaced with optimized ones.
MSPT (milliseconds per tick)
The MSPT (milliseconds per tick) metric reports how many milliseconds on average is taken by the game to process each tick.
For a normal, lag free experience, the magic number is 50 or less milliseconds per tick. If a tick takes longer than 50 milliseconds, the execution of the next tick has to be delayed, as ticks cannot execute in parallel. When this happens, the gameplay experience starts to deteriorate, as things become less responsive and "laggy".
The Minecraft server aims to run exactly 20 of these game "ticks" every second, or in other words, one tick every 50 milliseconds.
You can see how the duration of each tick varies with the command /mspt
provided by spigot.
