Inference Optimization Technology Evolution: PagedAttention / FlashAttention / Speculative Decoding Deep Dive
· 8 min read
LLM inference performance = Algorithm + Software + Hardware. Hardware (H100, B300, Rubin) only determines the theoretical ceiling. Actual inference performance can be improved 5-30× through algorithmic optimization. This article provides a deep analysis of the three major inference optimization technologies: PagedAttention, FlashAttention, and Speculative Decoding.
