Benchmarked every spec-decode method on Qwen3.6-27B across vLLM and SGLang (single RTX PRO 6000 Max-Q)

Explain Like I'm Normal

A community developer benchmarked various speculative decoding methods for Qwen 2.5/3.2 series on a single GPU to see which engine actually delivers speed. DFlash emerged as the winner, providing up to a 3.3x speedup on SGLang, significantly outperforming EAGLE and standard ngram approaches. This data helps builders choose the right inference stack to minimize latency without needing massive compute clusters.
