TITLE: Port 4 Utilization
The percentage of cycles where uops are dispatched on port 4
Looking at the utilization of each individual port may provide insight into whether you are execution bound due to overutilization of certain ports.
If this metric is much greater than 50%, you may want to look at whether you are bound by utilization of this port.
EQUATION: UOPS_DISPATCHED_PORT.PORT_4 / CPU_CLK_UNHALTED.THREAD
