Need help fixing hit detection(Delayed hits)

[Stats]

Hello I am having a problem on fixing hit detection on my practice server. I currently run the server which is running on spigot-20141113a (1.7-1.8 compatible) Basically I have an issue where the hits on the server feel delayed. I basically tried a bunch of things. We use tick shuffle to remove an aspect of the well known "relog glitch" and we use "knockback fixer" to make the KB a little bit better. We use exactly 27 plugins (picture bellow this text). I run essentialsX so yeah. Basically I'm asking to know if there is any way I could fix the hit registration because It feels delayed. We also have 6GB of ram

Nevermind we got it fixed from a dev that implemented Asynchronous hit processing basically hit detection like kohi.
