Test Result of offload cost with QAT 8950

Hello all,

Recently, I am surveying the Intel QuickAssist Adapter 8950 and a parameter is confusing me.

The cost of offload is  the cycles consumed by the driver in sending requests to the hardware, and processing responses.

I have searched many documents provided by Intel, but I don't find the test result. I think this is an important parameters, which affects the choice on whether or not to offload certain operations.

Can someone has found the test result of offload cost  with QAT 8950?

Thanks sincerely!
