求助java 查600条数据为什么要3秒左右

用postMan只需44ms:
{"from":0,"size":1000,"query":{"bool":{"must":[{"bool":{"should":[{"match_phrase":{"news_id":{"query":"6507c8d8fa9e488eaa38662481ba647e","slop":0,"zero_terms_query":"NONE","boost":1.0}}},{"match_phrase":{"news_id":{"query":"5fe7cea4db07434caad4bdc53f59e72d","slop":0,"zero_terms_query":"NONE","boost":1.0}}},{"match_phrase":{"news_id":{"query":"f6988b2db1704bd3a7ee04638fb83c6a","slop":0,"zero_terms_query":"NONE","boost":1.0}}},{"match_phrase":{"news_id":{"query":"f86474c67c904b7cbe61c7336a8c6ddd","slop":0,"zero_terms_query":"NONE","boost":1.0}}},{"match_phrase":{"news_id":{"query":"20dc078c33964cc8a196cd5db4c7c0a4","slop":0,"zero_terms_query":"NONE","boost":1.0}}},{"match_phrase":{"news_id":{"query":"e280705c2cdc452bb5665284cc5bae96","slop":0,"zero_terms_query":"NONE","boost":1.0}}},{"match_phrase":{"news_id":{"query":"16e1560981ed4d3eb6fdc089a7bf9c9c","slop":0,"zero_terms_query":"NONE","boost":1.0}}}],"adjust_pure_negative":true,"boost":1.0}}],"adjust_pure_negative":true,"boost":1.0}}}
java就这一句需要几秒, 查询条件一样:
SearchResponse response = getRestHighLevelClient().search(searchRequest,RequestOptions.DEFAULT);
