Curious slow down from script

Using this script I wrote slows everything down to a crawl, and I don't know why:

Code (csharp):

1. #pragma strict

3. private var lerpPosition : float = 0.0f;
4. private var lerpTime : float = 3.0f;

7.  
8. private var TeleportTarget : GameObject;
9.

It is a JumpPoint / Teleport script. It's on ~ 8000 objects in the scene. Everything in Start sets up the connections between Jump Points. That part I expect to be very slow, and indeed it is. You can tell when it finishes running because the particle generator attached to the camera starts moving its particles.

If I comment out this line in OnTriggerStay, the game runs at normal speed once Start finishes.

Code (csharp):

1.  other.transform.position = TeleportTarget.transform.position;

So it seems the problem is there. But if I understand the function correctly OnTriggerStay should only be called when my Player Ship moves into the Jump Point Trigger collider. (There are no other moving objects in the game right now.) The code in the If then only is called once the Player Ship has been lerp'd into position. So why is this line of code slowing everything down?

The code in OnTriggerStay is supposed to move the Player Ship to the center of the collider, and then move the ship to the TeleportTarget. It does do its function when I fly the Player Ship into it. The script just makes the game very slow.

Thanks.
