Lagg! HELP PLEASE!

I have a very famous swedish minecraft server. And everything is doing good so far, until i enter the north part of the main city!

I will post a screenshot och the part...

I have no idea what could be causing the lagg, and sometimes minecraft crashes when i enter the area!

I need help ASAP! ;(

Help please?

Perhaps because that's the place where you run a lot of stuff?

//remove items 10000

//butcher

//butcher -a

What will those commands do?

If you have the plugin worldedit:

//remove items 10000

This will remove dropped items laying on the ground, which may be the cause of lagg.

//butcher

Kill mobs in a certain area

//butcher -a

Never used that but I guess -a stand for all. So it probably kills all mobs in your world.

You might want to remove tnt, water flowing, lava flowing;causes laggs

Didn't work

Using a lot of redstone?

nope

Can u tell us what kind of plugins u use? (mob arena there?)
And what u do i thT part of ur city?

Yes there is a mobarena there, and it is the north part of the city!

Try putting the plugin out and in, maybe outdated?

Mobarena?

Yes

You should download NoLagg, and ClearLag.

I have nolagg and Clearlag installed and configured!

still lags

Then i suggest you check ALL your plugins for most stable versions and pray to notch that he helps you

Ohh i see! It's not your server lagging it's you! What you need to get is OptFine, but even with that you may still lag considering your processor can't handle a small game like minecraft

not needed, i fixed the lagg
