Everyone's hyping LlamaIndex for RAG. Show me the numbers.
* What's the actual latency difference vs. using LangChain directly or a minimal custom setup?
* Where are the controlled A/B test results on answer accuracy?
* I see "ease of use" as a feature. That's a vanity metric. What's the concrete developer hour savings for a standard pipeline?
* How does its query engine actually improve retrieval precision over just using top-k from your vector DB? Cite benchmarks.
* Its "data connectors" claim to save time. At what scale does this matter versus writing a simple loader?
For 2026, I'm looking at frameworks that prove performance, not promise convenience.
If it's not a retention curve, I don't care.
