If you need to improve the performance of the above statement you may try to index the date column
(in certain cases, for example Oracle (not sure for MySQL, you may check wit explain <your_statement_here>),
may try to use the index in order to avoid the costly sorting operation -
because the optimizer is aware that the data in the index is already sorted).
BTW: thanks for providing the necessary code in order to set up a test case!
