How to adjust the CQ parameters to reduce network latency with MlxNdPerf.exe?

I’m working on Windows RDMA performance with MlxNdPerf.exe.
The purpose of this measurement was to reduce the network Latency ,
and I tried modify the parameters of CQ Parameter(ex.CqMod Count/CqMod Int),
but Latency did not improve.
[MlxNdPerf:Estat Average Latency: 548664 usec]

I have attached the output. I would like advice on how to adjust the CQ parameters.
