Seconded. I understand that Timescale extends Postgres, but I'd still like to see performance comparisons relative to other time-series databases such as InfluxDB or even TiDB.

Shameless self-plug: we're also building database technology, but for embedding vectors (https://milvus.io) rather than time-series data - when doing query performance comparisons, we get several orders of magnitude of performance improvement over traditional databases. It's an unfair comparison, so we generally avoid it.
