The Whetstone benchmark produces an overall performance rating in terms of Million Whetstone Instructions Per Second or MWIPS. This, and other later versions, measure the speeds of individual test functions in Million Operations or Floating point Operations Per Second (MOPS or MFLOPS). Note that, using the same software and processor model, measured speeds can be expected to be proportional to CPU MHz. http://www.roylongbottom.org.uk/online/whetjava.html
