I have a group with an internal network, not connected to any outside nodes.

The internal network consists of 8 subnetworks each containing:

input: "X to scalar" and "Z to scalar"

a "negate scalar" connected to the "Z to scalar"

two "build vector" nodes building from the above 3 nodes the vectors [X, X, Z] and [-Z, Z, X]

a "cross_product" node multiplying above two vectors creating a vector [X^2-Z^2, -(X^2+Z^2), 2*X*Z]

an "add_vector" adding a "constant_vector" to above generated vector generating the output of this simple network.

The input of the following 7 subnetwork are connected to the output vector of the previous subnetworks.

This simple networks has the complexcity (only counting nodes the should use cpu time):

8 negations 32 additions 24 multiplications.

The attached tgc contains this structure.

**BUT IT TAKES ABOUT 10 MINUTES TO LOAD USING 50% OF THE CPU"**
