Brute-Force Vector Search Outperforms Complex Databases for Small Datasets
July 31, 2026
For datasets up to 1 million documents, NumPy-based brute-force dot product operations achieve sub-15ms latency on consumer hardware like the M4 MBP. This approach avoids the operational complexity and cost of dedicated vector databases for low-traffic, small-scale retrieval tasks.
HOW THIS AFFECTS YOU
●
builderYou can replace expensive vector database infrastructure with simple NumPy operations for datasets under 1M vectors.
●
founderYou can significantly reduce infrastructure overhead for early-stage products that do not yet require massive scale.
