Lag in server with fragnet 50 slot,plugins ?

hello , does anyone know if there are some things i need to disable in any of my plugins , like feks
essentialschat , maybe ???.. i got a feeling of that its saving logs and that makes it lag , ITS ONLY A GUESS , but does any recognize any of these plugins that could make my server lag badly ?
i get those BIG long lag spikes , and then smooth , BIG long lag spikes and smooth, its really annoying , it happends most when new players joins , it almost feels like one of my plugins are using really much space to make a log ... ill give a list of what i have

orebfuscator , groupmanager , worldedit, iconomy ,bukkitcompat,
log, narrowtuxlib,essentials , simpleregionmarket,
essentialsspawn , vanishnopacket,essentialschat,factions,moneydrop
showcase,vault,and mobdesguise



no one is using mobdesquise , pretty much only me , but i hardly ever
use it , i tryed uninstalling it , but same lag spike

does anyone notice a plugin i have that could cause it ?
thanks

 

It's probably because you don't have enough ram/bandwidth to host that many people.

How much ram is allocated to the server?
How much bandwidth do you/your hoster have?

 

its 4 gig , its suppoed to hold 50 without any lag ,
and me and a mate was the only one on , it didnt matter how many people joined , it was the same lag spike ,

 

have you actually allocated the full 4 gigs to it?

 

I would recommend speaking with the host about this as they would know best.

 

actully no i did talk to them for 7 hours

 

The only plugin that stands out is Orebfuscator. Radius and cache size can have a large effect on CPU utilization.

The easiest way to be sure what's causing the problem is to run without plugins for a period of time (whitelist while you do this) and/or run with a newly generated world. From the sounds of it you'll know fairly quickly if either helps.

 

Probably an overloaded node.

With shared hosting like this, you are not guaranteed performance.
