Zvec: A lightweight, fast, in-process vector database

Their self-reported benchmarks have them out-performing pinecone by 7x in queries-per-second: https://zvec.org/en/docs/benchmarks/

I'd love to see those results independently verified, and I'd also love a good explanation of how they're getting such great performance.

Did someone compared with uSearch (https://github.com/unum-cloud/USearch)?

I thought you need memory for these things and CPU is not the bottleneck?

Are these sort of similarity searches useful for classifying text?
