kkewwei opened a new issue, #16076:
URL: https://github.com/apache/lucene/issues/16076

   ### Description
   
   In #15140, we introduced TernaryLongHeap to optimize performance for 
collectors such as TopDoc*Collectors. Nevertheless, TopFieldLeafCollector still 
adopts a 2-ary PriorityQueue, which causes identical performance bottlenecks 
even with a topN value of 1000.
   
   Would it be feasible to implement a ternary-heap based PriorityQueue as well?
