This is really useful information. I'm also running a very similar setup and had planned to provide some numbers this weekend but the information you've provided is so much more in depth. Also, your numbers are far better than mine so I will spend some time comparing configurations and report back if I can tweak things and achieve the same results. To give a very rough idea of what I'm seeing: 10920x, 128GB quad channel DDR4, 2 x 3090 over dual 16x PCIE3 with p2p (but no nvlink). Caps out at around 122 tok/sec with ~300k context running CTX=fast.
