This might be a stupid question: For the record, can you please provide a
mathematical formula for calculating the percentage improvement in
time/memory? For example, if p1 is the previous performance time and p2 is
the new and improved performance time, how do I calculate the percentage
improvement? This assumes that both p1 and p2 are both expressed in the
same unit of measurement, e.g. seconds.
