Recently，we upgrade our es cluster to 7.2.0 and find the same search took time is longer than 6.8.0 . so we prepare for two cluster (7.2 and 6.8) with same index data set , same mapping, and execute same search. we found that 7.2.0 is slower than 6.8.0, our tests below: 7.2.0 index list: 6.8.0 …

7.2.0 spend more time on query `next_doc` and aggregation `collect` than 6.8.0
