@yanliang567 thank for applying. 1. v2.0.1 is better than v2.1.0，but not that better; 2. Yes，it's a clutser deploying by helm. Here is whole logs in milvus. [logs.tar.gz](https://github.com/milvus-io/milvus/files/9335331/logs.tar.gz)

@xiaofan-luan Yes, my 5 querynodes share the three machines which two have 32 cores and another has 20 cores.

> 1 replica will cause qps decreased. I got that increasing replica will increase the thoughtouput.

@yanliang567 Thank you for answering. - the network latency is ok. Both the client and server are in the same two machine. And the latency is also got from milvus...

@yanliang567 I just run the office code and get the flowing result and all config is office default. [2022-08-18 19:44:48.818][ INFO] - Name # reqs # fails | Avg Min...

@yanliang567  I reduce querynode num from 8 to 2 and I got this result. Here is my querynode cpu and memory config:  I guess it is still far...

@yanliang567 I wonder how many querynode is configed under the office benchmark test and how the replicas is configed.

> This is amazing! Mine test has two query node in 20 cores host machine and has one replica, but mine test result really can not reach so good performance....

I have another question. When I increase the nq and the qps is significant decreases.Here are the result: - when nq = 1, I got this -> qps =124 ...

@yanliang567 Yes ，I have tested the difference in my datatset. I have notice that My replicas group num keeps 2 when I increase replicas. And I wonder it's normal? Here...
