Hi @janeks the memory usage is dependent on many different factors which makes it very hard / impossible to calculate on forehand. In other words I don't think it can be avoided. However, if you have specific suggestions for performance improvements please let me know what sections / code and I will look into it. Or if you can create a branch with a test case containing this specific example I can possibly find a bottleneck and improve this. So I'll close this for now but if you can provide a failing test case I can reopen it.
