What is a the Python code you requested given the following:
Complete the below
def benchmark(scale=1):

    ''''Benchmark and return information regarding the relative performance of a
    protocol which does not use the buffering mixin and a protocol which
    does.
    @type scale: C{int}
    @param scale: A multipler to the amount of work to perform
    @return: A Deferred which will fire with a dictionary mapping each of
    the two unicode strings C{u\'buffered\'} and C{u\'unbuffered\'} to
    dictionaries describing the performance of a protocol of each type.
    These value dictionaries will map the unicode strings C{u\'connected\'}
    and C{u\'disconnected\'} to the times at which each of those events
    occurred and C{u\'duration\'} two the difference between these two values.'
