DFlash Boosts Local Qwen Inference Speed by 2.2x
techNmak · x · 2026-07-14
This repost summarizes Atomic Chat's tests on DFlash, which significantly accelerates the locally run Qwen3.6-27B.
Benchmark Results
- Baseline: 44 tok/s, 1.00x
- MTP: 65 tok/s, 1.45x, 71% accepted
- DFlash: 98 tok/s, 2.20x, 30% accepted
Mechanism
- Baseline: Generates 1 token per step
- MTP: Model internally guesses 3 tokens at once
- DFlash: A separate small model writes 15 tokens at once, verified by the large model
Phenomenon
The hit rate is significantly higher for repetitive tasks like JSON generation, pushing speeds up to 152 tok/s (3.4x). However, the performance gain drops for story-generation tasks.
