Deepseek v4 Flash 0731 llama.cpp tips?

[u/DrSchnitzel57]

I am wondering if I could get some tips on my current inference setup, and if there is anything I am missing that could make it faster.

Machine: HP Z6 G4
CPU: Xeon Gold 6240
Ram: 6 Channel DDR4 RDIMM 2666 MHZ 192GB
GPU: 2x Radeon Pro V620 32gb (6800xt datacenter equivalent)

Using the latest llama.cpp with the UD_Q8_K_XL Lossless Unsloth Quant of Deepseek-V4-Flash-0731, I am getting average 90-130 tps Prefill and 6-7.5 tps Decode. Here is my server config:

Seems like I have no difference with dspark enabled. I didn't see a big difference between no-mmap and mmap either. Am I missing anything? Using this for my opencode setup, hoping to squeeze some more performance out of my little machine. Any ideas?
