Did a bit of testing and thought I'd post the result here.
I tried this with Qwen using LM Studio on B200. The headline result was better than I expected, but speculative decoding still ended up being the limiting factor.
Curious if anyone else landed in the same place.
This is mostly for local work rather than public serving.

Ran a quick check on my box. On dual 3090 with PyTorch, I saw basically the same behavior.

I tested this tonight. My result was mixed: first run looked bad, second run looked normal. The surprise was that memory pressure showed up before throughput collapsed.

That matches what I was seeing. I ended up in about the same place using SGLang. I got better results once I stopped chasing one metric and just looked at whether the workflow felt usable.

Thanks, that helps. That matches what I saw on 7900 XTX.

I'd start with the simpler stack.

Did a small comparison this afternoon. My result was mixed: first run looked bad, second run looked normal. The main thing that moved was latency, not quality.
