Why Speculative Decoding (SD)? Decoding is memory-bound: loading KV cache and model takes a long time memory-bound cases: big matrix * small matrix; vector * matrix → O(n^2) compute-bound cases: lar

Why P/D disaggregation? Initial scheduler logic in vLLM: prioritize prefill for good throughput Problem: prefill may slow down other requests’ decode How to mix P and D together? Well, even thei
