One 10-second download and upload per destination, three concurrent streams, IPv4 over HTTPS, with no configured rate limit. HTTP latency and jitter are application-level measurements; packet loss was not measured. These paths do not establish maximum link capacity.
Separately reviewed later observations on this same deployment. The original capped iperf path checks remain under Evidence; their values and test window are unchanged.
Outbound traffic has a monitored byte-abort threshold with sampling and termination overshoot; an aborted transfer is unscored.

PostgreSQL performance

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.
24-hour consistencyNot measured
Workload skipped · No measured score. This report covers a 21 min test window, so no time series exists and none is drawn.
| Repetition | CPU 1 thread | Memory read | Random read | PostgreSQL |
|---|---|---|---|---|
| 1 | 1,343 events/s | 13,154 MiB/s | 65,569 IOPS | 3,140 tx/s |
| 2 | 1,326 events/s | 14,821 MiB/s | 69,684 IOPS | 3,430 tx/s |
| 3 | 1,344 events/s | 15,880 MiB/s | 71,069 IOPS | 3,092 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.
- Provider, region and SKU were matched to retained deployment records. Missing detected values use operator-supplied context and remain labelled supplied. 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.

Historical capped network path checks
