This was almost worthless. he used a brand new world that wont have lag anyway, instead of a world that is acrtively suffering from lag to show a before and after. he also explained it in ways that confuse people into thinking it doesthings it doesnt. Basically this was a 4min video of how to install a mod. Great. This doesnt improve server stability, it improves tick lag, not framerate lag or other sorts of lag. He also didnt even credit the mod author.
