Median of 3 passed runs of about 30 seconds per dataset. Latency percentiles were not measured.
Consistency across runs
One deployment · repeated runs inside the recorded test window.
Workload skipped · No measured score. This report covers a 20 min test window, so no time series exists and none is drawn.
| Repetition | CPU 1 thread | Memory read | Random read | PostgreSQL |
|---|---|---|---|---|
| 1 | 1,642 events/s | 26,550 MiB/s | 72,186 IOPS | 3,948 tx/s |
| 2 | 1,641 events/s | 27,240 MiB/s | 73,238 IOPS | 3,995 tx/s |
| 3 | 1,638 events/s | 27,273 MiB/s | 72,854 IOPS | 3,868 tx/s |
Individual runs, not medians. PostgreSQL uses the in-memory dataset. Spread within one test window does not establish long-term consistency.

Review and measurement limits
- Single deployment; not an independent three-instance cohort.
- No hardware attestation.
- Pilot memory implements read/write; copy workload deferred.
- Network endpoints must be supplied by the operator; no public third-party servers are used.
- Database latency distribution is not available from this pilot parser; average latency only.
- This profile is not a full implementation of all proposed methodology tests.
- Resource-constrained environment: CPU workers and RAM reflect affinity/cgroup limits, not host capacity. Private resource-limits evidence retains both; do not merge container/VM or architecture cohorts.
- Short profile: does not establish 24-hour consistency.
- This report received AI-assisted evidence review under user-delegated authorization. This is not independent human verification or hardware attestation.
- This pilot measures its recorded test window. It does not establish 24-hour consistency, long-term reliability or provider-wide performance.
- Network tests use two controlled endpoints, one stream, a 100 Mbit/s rate setting and a requested 64 MiB byte target per direction. Reverse-mode polling can exceed that byte target; actual sent and received bytes govern traffic accounting. These results do not measure maximum link capacity.
- Provider, region and SKU were matched to retained deployment records. Missing detected values and deployment locations within a detected Hetzner network zone use operator-supplied context and remain labelled supplied. The original detected network zone is retained privately; the detected datacenter zone remains in the report. Control-plane records and checksums do not attest the physical host or establish physical-host independence.
- Package versions and available guard and journal evidence were reviewed. These records do not establish continuous absence of package activity throughout the test window.
- The pilot includes memory read/write and average PostgreSQL latency. Memory-copy tests and PostgreSQL latency percentiles are not implemented. Skipped consistency and missing measurements are not scores.
- These network observations were collected during provider-reported maintenance on core routers. They are not a normal-path baseline. The status notice does not establish that maintenance caused any individual measurement or any CPU, memory, disk or database result.

Historical capped network path checks
Original full benchmark deployment · 17 Oct 2026. These controlled iperf path checks used a 100 Mbit/s rate setting and do not measure internet speed or maximum link capacity. RTT is the probe mean; jitter and packet loss were not measured. The original report JSON retains these measurements.
