Thanks. I note a different aspect of SoA is when different functions or loops involve only a subset of the feilds, only the arrays of the involved fields are fetched. With AoS the feilds are scrunched in memory next to each other byRecord. That could benefit algorithms which only touch some of the records, however every record usually needs accessed to see whether its involved or not - the 'involving feild' would need stored separately for AoS to have any benefit.
