hi,  
I use elasticsearch-py to search doc in elasticsearch . when i try to search doc under concurrent conditions , the time consumerd increased . I computed and traced the time consumed by urllib3(elasticsearch-py default http client) 。It seem like the same batch of requests took time to increase cumulatively。

the log format is :  
\<conneciton object,thread name, the request num summed up in the urllib3 pool , time consumed by http request \> . Different threads saw the same "request num " can be recognized as the were in the same batch 。 Such as : the first connection that returns the result with "request num" 810 consume time 0.006xx ms , it was normal 。 However, the subsequent request consumed time is constantly accumulating。 I want to know if there is any synchronization on the server side.

elasticsearh version is 6.4.2, elasticsearch-py version 6.3.1  
elasticsearch search thread pool config is :  
thread\_pool.search.queue\_size: 500  
thread\_pool.search.size: 100  
thread\_pool.search.min\_queue\_size: 10  
thread\_pool.search.max\_queue\_size: 1000  
thread\_pool.search.auto\_queue\_frame\_size: 2000  
thread\_pool.search.target\_response\_time: 6s

query is simple:  
{ 'query': {'match': {'question': 'xxxxx'}}, 'size': 10, 'from': 0}

In order to verify the problem, I did not use the any plugins .

thanks!
