> less "code branches" than duckdb, which may or may not translate to faster performance.

In that case it was about 2.5x faster than DuckDB end to end, so a bit less than the difference in branches.

If you want to see some independent benchmarks on Umbra, our underlying technology, its currently first place on Clickbench [1]. You can compare against duckdb there as well.

clickbench is a toy benchmark: small dataset, very specific queries.

Benchmarking full tcp-h (not just one query like in your post) on sizable dataset (few TBs) would be very good close to real world scenario, but vendors usually avoid this.

There are TPC-H numbers in another post: https://cedardb.com/blog/simple_efficient_hash_tables/

its great starting insight, but again its small dataset (100GB) which almost fits memory, and I think many details are missing (for example clickbench publishes all configs and queries, and more detailed report, so vendors can reproduce/optimize/dispute them).

> small dataset (100GB)

What counts as large or small definitely varies a lot depending on the context of the conversation/analysis.

MotherDuck's "Big Data is Dead" post [0] sticks in mind:

> The general feedback we got talking to folks in the industry was that 100 GB was the right order of magnitude for a data warehouse. This is where we focused a lot of our efforts in benchmarking.

Another point of reference is [1]

> [...] Umbra achieves unprecedentedly low query latencies. On small data sets, it is even faster than interpreter engines like DuckDB

> TPC-H Small Dataset = 866k tuples, sf 0.1

and then user discovers that DuckDB is plagued with OOMs and dramatic performance degradations when his data is slightly larger than memory.
