LocalLLaMA user reports performance drop with MTP optimization

By PulseAugur Editorial · [1 sources] ·

A user on the r/LocalLLaMA subreddit is experiencing a significant drop in performance and GPU utilization when enabling "MTP" (likely Multi-Threaded Processing or a similar optimization) while running the Qwen 3.6 27B model. The user notes that this issue is not memory-related but rather a decline in processing speed, and they are seeking explanations for this behavior. They speculate that potential causes could include bus contention due to PCIe risers or issues with the Vulkan API. AI
