The CPU output from the TOP command can not be used to determine dataplane load.  The pan_task processes are always at 100% CPU utilization as they are the individual software processes which perform packet processing on the dataplane..

This is design behavior of TOP Command in IRIX Mode where It is possible for the % CPU column to display values that total greater than 100%
Solaris mode divides the % CPU for each process by the number of CPUs in the system so that the total will be 100%.
To Toggle IRIX Mode off press Shift+I:
