Frequently Asked Questions
5 questions
Pinecone delivers faster results with < 50ms p99 latency and 5+ million RPS throughput, thanks to its fully managed infrastructure and proprietary optimization. Weaviate achieves 50-150ms latency and 2-3 million RPS, which is still suitable for most applications but depends heavily on your self-hosted infrastructure quality. For latency-critical applications (sub-50ms requirements), Pinecone is the better choice.
