Describe your question in detail.

Hey folks,
I've been running some TPS benchmarks comparing Diem and Aptos on the same hardware setup, and I'm seeing a pretty big gap in performance.
With Diem, I'm getting around 120K TPS, but with Aptos, it's only hitting around 45K TPS on the exact same setup:
CPU: AMD EPYC 7B13 (32 cores / 64 threads)
RAM: 128 GB
OS: Ubuntu 18.04.6 LTS (Kernel 5.4.0-1125-gcp)
CPU Speed: 2.45 GHz

I'm trying to understand whether this kind of performance difference is expected. Is there something fundamentally different in how Aptos handles execution that explains this?
Appreciate any insights or pointers!
