I ran the same model on a Spark through plain diffusers (bf16, no container) and posted timings here: Qwen-Image-2.1 on DGX Spark: 54 s per 1024² image (40 steps), 31.6 GB, and a fix for the pink vertical line
1024² / 40 steps: 54 s, ~31.6 GB. Did you get any numbers out of vLLM-OMNI? Curious whether it beats diffusers on the GB10.
