Excelsior JET Benchmarking Results

Recommended Posts

???I read the Excelsior JET Benchmarking Results.  I do not understand what the x-axis,  -- the percentages represent.  Could you explain what the percentages represent and what they are relative to.  This would be very helpful.

Thank you

Some benchmarks yield an abstract "score", and usually the higher the score, the better is the result. When you measure execution time, it is the opposite - the lower the time, the better. So we introduced a performance index to normalize results of different benchmarks so that they can be meaningfully shown on one chart.

For each benchmark, the result shown by the reference implementation (Sun HotSpot Client VM) is taken for 100%. If the result of the given VM is 2 times better, i.e. either execution on that VM took just half of the HotSpot Client time, or the score is 2x the HotSpot Client score, the index is 200%. If it is two times worse, the index is 50%.
