Benchmarking in the wild: real-world constraints, debates, and what performance claims mean for large customers

Benchmarking for large customers is back in the spotlight. The core question: should teams publish real performance benchmarks, or keep them private? A discussion about catering to a large customer's benchmark request highlights the problem: there’s no other market reference to anchor claims ^[1].

Real-world constraints — Benchmarks collide with logs and analytics realities. Real workloads, data locality, and distributed systems make apples-to-apples comparisons hard, so publishing a single benchmark may help some customers but confuse others if environments differ ^[1].

Cross-engine comparisons — In the wild, teams compare Snowflake and BigQuery against open-source options like DuckDB. A 1T-row aggregation on 63 Azure Standard E64pds v6 nodes finishes in about 5 seconds, underscoring scale and cost tradeoffs ^[2]. Open-source DataFusion Ballista is cited as a path for cross-engine planning ^[2].

The cost puzzle — That 63-node run costs about $235.872/hr on demand; a Snowflake 4XL cluster would run around $384/hr. Spot instances could drop to about $45.99/hr, but reliability and data locality come into play ^[2]. The numbers echo a broader pattern: performance claims live or die by context ^[2].

What it means for large customers — Benchmarks help, but real-world constraints—logs, analytics, distributed systems—mean no one-size-fits-all. The debate will keep fueling apples-to-apples when possible and transparent disclosures when not ^[1][2].

Closing thought: watch how this evolves as teams push for practical benchmarks that matter to enterprise buyers.
