Reduce the total mob spawn or maybe a plugin who do that

Less mobs = Less lag.

The actual mob removers dont remove the total number of mobs, so if you remove zombie and squids, it will spawn the misses zombies and squids in other form, like sheep, cow, etc...

 

There are a few plugins that do this. One being "Perfomance Tweaks"
You can find it here by searching : http://plugins.bukkit.org/#ti=mob&ta=all&au=

Other wise known as Performance Tweaks

Its actual purpose is to improve server stability and speed.
It serves two main roles.

A.It creates a sort of non volatile Ramdisk for chunks meaning you use a lot less HDD I/O
B.Allows you to limit TOTAL Mob count per world. Allows you to se a MAX amount of mobs to ever spawn per world per mob type.

Example

World1
MaxMonsters:500
MaxAnimals:200

World2
MaxMonsters:250
MaxAnimals:100


Hope it suits your needs.
