Defining Performance
• PerformanceM = 1/Execution TimeM
PerformanceM1 > PerformanceM2
1/Execution TimeM1 > 1/Execution TimeM2
Execution TimeM2 > Execution TimeM1
• Machine M1 is n times faster than M2
PerformanceM1 Execution TimeM2 --------------------- = n = ------------------------PerformanceM2 Execution TimeM1
