c# script execution performance.

Hey.

I would like to ask about performance of c# component execution.
I'm working with millions of points so I've made my own OcTree class (with AABB and Vector stuff)
Now I'm testing basic components for OcTree like AABB to figure out if all functions work correctly by comparing them with GH components.

I also used Stopwatch method form System.Diagnostics to measure the execution time for judging the performance.
(As I mentioned before I'm using my own Vectro3 class, do i need to convert Vector3d to my Vector3)

Building AABB is taking 160 ms conversion 200 ms so in total is more ore less 360 ms.

Why whole component need almost 12 sec to be executed??

Thanks in advanced.
