LocalLLaMA thread diagnoses slow Qwen3.5-27B Q8 on Ollama

This looks less like a raw hardware problem and more like a local inference configuration mismatch where Q8 plus context can silently trigger costly offloading.

• –Commenters note Q8 for a 27B model can consume most available VRAM, leaving too little room for KV cache.
• –Several responses recommend moving to UD-Q6 or Q4 variants for a better speed/quality tradeoff.
• –The thread highlights a recurring local-LLM issue: convenient defaults in Ollama can obscure performance-critical settings.
