WebA heap-backed PQ has O (1) time to see the top element and O (lg n) time to dequeue the top element. With p = number of priorities, your queue has O (p) time to look and O (p) time to dequeue (assuming I've analyzed your queue implementation correctly for O (1) and O (1) ). Your implementation is basically as fast as it can get for small p.
