• The maximum number of instructions executed per second is halved
• The maximum number of instructions executed per second doubles
• Performance decreases
• The maximum number of instructions executed per second quadruples

If the processing speed goes up from 1GHZ to 4GHZ – what is the exact effect on the performance of the computer? (1-4)

• The maximum number of instructions executed per second quadruples
• The maximum number of instructions executed per second is halved
• The maximum number of instructions executed per second doubles
