How we tested
We provisioned identical workloads on CirrusStack and five competitors from three probe continents, running each test for a full week to smooth out diurnal swings. Every config, script, and raw result is published in the companion repository.
How we tested
The harness drives production-shaped traffic — 80% reads, 20% writes, bursts every 15 minutes — against region-pinned deployments. We report medians, not averages, and we discard the first hour as warm-up.
Results
- Median latency: 41 ms, best in class for the region
- 99th percentile: 118 ms, within 8% of the leader
- Throughput under burst: degraded gracefully, no errors
- Cost per million operations: $0.89 — second cheapest of seven
Results
The headline number hides the more interesting one: consistency. CirrusStack's p99 stayed within 2.4x of its median across the whole week — the tightest spread we have measured this year.
Where it struggles
Cold operations are the weak spot. First-touch restores and scale-from-zero events trail the market leader by double digits, which matters for bursty archival workloads more than for steady-state apps.
Bottom line
None of this changes list pricing today. It does change the calculus for teams choosing where to standardize next, and CloudRadar's comparison tables are updated to reflect it.
