Question

I have multiple instances in code where we have done StringComparison.CurrentCultureIgnoreCase for equality comparison of two strings.
Given,
– In our code strings are based on single culture (en)
– There would ‘rarely’ be a case of two strings just varying in case (atleast for most of the values).

I am looking for some opinion on how expensive (performance) is StringComparison.CurrentCultureIgnoreCase than the default stringOne.Equals(stringtwo). If the difference is considerable I would do one full iteration of code and remove at all the places where it does not make sense (for instance, comparing RecordId like this).

Thanks for your interest.
