[zhangchenglala]

There is a phenomenon in the mishard running test. Every 5 minutes, the request will usher in a larger wave of delay, and a single request exceeds 1000ms.
The query log found that milvus has fewer slow queries.

mishard运行测试中有一个现象，每隔5min，请求就会迎来一波较大的时延，单次请求超过1000ms。
查询日志发现，milvus慢查询较少。

Is there any other actions along with search? For example, one client continually insert vectors, the other continually search.
How many vectors in the collection? Same search parameter every time?
