I think your problem lies within NoCheat. NoCheat makes a (small) math calculation every time a player moves around. When you have ~100 people moving around, it is making quite a few calculations every second.

 

That didnt help :/ But thx anyways

 

Try McMMO

 

No didnt help

 

If you have over 70-150 all day why dont you ask them to donate for a dedicated server?

 

the server is dedicated

I really doubt that it will help, but we are on Java 6.27 now, not 6.18. Maybe you want to try going to the latest patch.

 

i updated it via SSH today, not sure why it didnt work.

 

Did that fix it for you? I have noticed this problem too. It's VERY annoying.
