- DFlash speculative decoding bench reproducing joaosump's methodology: 2 warmup requests + recorded request against llama-server /v1/chat/completions. Recorded request used temperature=0, max_tokens=500, prompt: Write a Python binary search tree implementation with insert, search, delete, and traversal methods. DFlash acceptance on recorded run: 451 accepted draft tokens out of 697 draft tokens (64.7%) -- workload-equivalent to joaosump's 452/693. Wall-clock 155.94 t/s; server-side eval rate 159.62 t/s. Same target + draft combo as joaosump's #1 entry (UD-Q4_K_XL fp_target + q4_k_m DFlash draft); same buun-llama-cpp build (one commit newer at 7343d30c6 vs his 30759dfa0). Server launched with -c 4096; DFlash recurrent backup makes usable slot n_ctx 2048.
