    I recently improved my efficiency by instead of querying select, just adding a primary index to the unique column and then adding it. MySQL will only add it if it doesn't exist.

    So instead of 2 statements:

     Query MySQL for exists:
         Query MySQL insert data
    

    Just do 1 and it will only work if it's unique:

    Query MySQL insert data
    

    1 Query is better than 2.
