Thank you for your kind comment. I checked out the the KB articles about even and odd core handling. When I've run both tests(12core and 8core), I found that even numbered core load hit 80% and started to use odd numbered core's resources. I tried the load testing with higher and lower TPS volumes, but the results showed similar tendencies. Test results that I got by GUI and CLI(tmsh show sys cpu) and seems to be same.

 

I am thinking it might the problem caused by our enviroment that I am using LTMs with OpenStack...?
