Summary

User reports Qwen3.8 27B at roughly 5–6 t/s on Strix Halo with max GPU offload. Setup is Windows + WSL2 + Docker, LM Studio with the Q4_K_M GGUF, Open WebUI frontend, and 262K context with context compaction enabled. The user calls the experience poor: refining a 12-slide deck repeatedly stalled for minutes and returned nothing across 3–4 retries, and asks whether the model, the 262K context, LM Studio, Open WebUI, or the stack is at fault.
