ABSTRACT:
A method and apparatus for a method for measuring performance of an I/O bus. The method includes the steps of (a) determining a number of I/O bus clock cycles that occur during I/O bus transactions involving a peripheral device during a time period, and (b) determining a bus performance value for the I/O bus based on the number of I/O bus clock cycles determined in step (a). One embodiment of the apparatus includes a mechanism for determining a bus utilization value for the I/O bus based on the number of I/O bus clock cycles counted by the counter. Another embodiment of the apparatus includes a mechanism for determining a bus efficiency value for the I/O bus based on the number of I/O bus clock cycles counted by the counter.
