We get questions about benchmarks from time to time. It’s a big topic, but as @trengrj mentioned, we have chosen to contribute to ANN benchmarks for comparative benchmarks https://ann-benchmarks.com/. (These relate to query performance.)
These benchmarks (though not perfect) are not vendor-maintained, and are probably as neutral as they get.
They’re not perfect as they don’t distinguish well between libraries with no network overhead and apis. But it will give you a great overview of the topic if you’re interested.
