Subect: Architecture-Performance

Performance is a subjective quatity that is often argued about by those who are affected by it. However we can make a general statement about performance: 

performance = 1 / (Execution time or response time)

The more general problem comes when we start agregating different performance metrics. Say we run 5 different programs and measure their running time. How do we agregate them? We can use a weighted average or a straight sum average.

Relative Performance 

                                    Execution Time of Y     1/Performance Y     Performance X
If X is n times faster than Y, n = --------------------- = ----------------- = ---------------
                                    Execution Time of X     1/Performance X     Performance Y

See ThroughPut, ResponseTime
