I have a feeling that saving it as a numeric field would be quicker. Numeric fields are generally quicker than alphanumeric fields and the date field in mySQL has the format of yyyy-mm-dd, so it probably does some error checking/validation to see the format is correct and also it contains alphanumeric characters being -'s. The best way to probably find out is to select a large amount of records in both formats and see which is quicker.
