Analyse the problem by using the tools your OS provides. Then write down your server specs and a concrete question.
I had with 20 Users 16 TPS, then i changed view-distance=10 to 5 and i had with 25 users 20 TPS (With DynMap, mcMMO, Falsebook and 50 other plugins with 1,8 GB RAM)
Hmm I think this is what I missed out on doing. Thanks for your help. I appreciate it Also would MYSQL do any difference? I'm just concerned seeing as I am not using that sort of program
Java command arguments that meet your system's specifications and using Java 7. Both great ways to optimize your server.
To me it sounds like you have a lot of plugins that may cause it and very little ram for running a big Minecraft server.
I know .. but my hoster don't want give me more ram i said him i pay 20 euro more, its okay .. but he said he cant -.-
