Closed as program error.
Error description
The performance degradation occurs because the logic detects the same variable when it was simply a variable and not when it was enclosed in a record. That enclosing caused the logic to think it was a different variable and hence needed to create a string to hold the intermediate value, instead of the higher performing logic.
Local fix
