Question about optimisation:

I have two classes, one class responsible for calculating physics, the other contains coefficients that physics uses for calculations.

```
public static class Coefficients
{
public static float[] someCoefficients {1,2,3}
}
public class Physics : Mono{
float[] localCopyOfCoeffs ;
void Start{
localCopyOfCoeffs = Coefficients.someCoefficients;
}
void CalculatePhysics()
{
//use coefficients for calculations
//Should I use
localCopyOfCoeffs
//or
Coefficients.someCoefficients;
}
}
```

Considering performance - is it much better to keep the local copy of coeffs (cache the reference) or should I just reference these coefficients directly in CalculatePhysics.
