All depends on the management.
What you do not see doesn't have to fully exist or be in render loop...

30000 polygons or triangles? Anyhow this is too much Man... You must
reduce it

Hello, developers!
I have a problem with a performance of own scene.
I try to build about 10 000 objects on scene with away3d. Now i have
over 30 000 polygons, a visible at once is about 500-2000. It required
~230 mb of RAM (Internet Explorer, AwayStats shows ~160 mb) and have
5-10 fps while camera is moving. It's to much RAM is using and to low
fps rate to me. I would be pleased for help in optimization of my
engine and for some advices about optimization tricks. As well I would
be pleased for pointing out my mistakes.
There are some screens:

I'm using Rectangle Clipping, obectCulling = true, Renderer = BASIC.
Material is ShadingColorMAterial with one light source.
I think about using LODObject, but it probably will be used more RAM
or not?
To limit the range of visibility i'm using following event code (on
move):
public function onMove(e:KSEvents):void
{
for each (var Obj3D:Object3D in
baseAway.view.scene.children)
{
if (baseCamera.position.distance
(Obj3D.position)>DistanceOfView)
{
Obj3D.visible = false;
}
else
{
Obj3D.visible = true;
}
}
}

Some code of class my object's class:
public class Tube extends KSMesh
{
...
Building faces:
for (var i:int = 0; i< (VertexArray[j] as
Vector.<Vertex>).length-1;
i++)
{
// first triangle of quad
var FirstFace:Face = new Face();
FirstFace.v0 = (VertexArray[j] as
Vector.<Vertex>)[i];
FirstFace.v1 = (VertexArray[j] as

FirstFace.v2 = (VertexArray[j+1] as
Vector.<Vertex>)[i];
this.addFace(FirstFace);
FirstFace = null;
// second triangle of quad
var SecondFace:Face = new Face();

var weld:Weld = new Weld(false);
weld.apply(this);
//

}
Tnx for help.
