A computer spends 80% of its time executing user?code and 20% of its time performing input/output operations. If you regard I/O as an unnecessary overhead, the efficiency of the computer is 80/(80 + 20) = 80%. Suppose that CPU performance is increasing at a compound rate of 40% per year and that the performance of I/O systems is increasing at a compound rate of 10% per year. In another two years, a new computer can be bought with both faster processing power and I/O performance. How efficient would the new computer be in two years’ time?
