Gemma 4 26B Hits 600 Tok/s on One RTX 5090

chain-77 benchmarked Gemma 4 26B with vLLM 0.19.2rc1, and DFlash raised output throughput on one RTX 5090 from 228 tok/s to 578 tok/s under 256 input tokens, 1024 output tokens, concurrency 1, and num_speculative_tokens=13.

Why it matters: HKR-H/K/R all pass: the single-GPU throughput hook is strong, and the post gives reproducible settings plus before/after speed. Reddit single-post evidence and one hardware setup keep it in the featured-threshold band.
