How do you diagnose a p95 latency violation in a RAG pi...

Do not start by optimizing components randomly. Instead, decompose the latency budget across the five design decisions. Recognize that prefill scales as 2P*T while search scales sublinearly with N. If retrieval exceeds roughly 15% of the total budget, the index is likely misconfigured, and you should investigate the retrieval mechanism specifically.
