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.

Outlook

Expect the next milestone in the coming quarter. CloudRadar will track the follow-through — pricing pages, SLA text, and real region availability — and update this piece if anything shifts.
