The prototype system is failing to react in time to these input events,causing noticeable annoyance to the gamers. You have calculated that you need to improveoverall system performance by 50%. This is to say that the entire system needs to be 50%faster than it is now. You know that these I/O events account for 75% of the systemworkload.
