Network performance

Source: San Francisco, US · two controlled London endpoints.

Destination	Download	Upload	RTT	Jitter	Loss
London endpoint 1	100.1 Mbit/s	97.3 Mbit/s	141.8 ms	—	—
London endpoint 2	100.0 Mbit/s	97.5 Mbit/s	136.9 ms	—	—

Results describe these measured paths at a 100 Mbit/s rate setting, not maximum link capacity. RTT is the probe mean; jitter and packet loss were not measured.

PostgreSQL performance

PostgreSQL 16.15 · pgbench · in-memory and storage-bound datasets.

Dataset profile	Transactions / sec	Average latency	Passed runs
In memory	1,644	2.43 ms	3 of 3 passed
Storage-bound	1,188	3.36 ms	3 of 3 passed

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 22 min test window, so no time series exists and none is drawn.

Repetition	CPU 1 thread	Memory read	Random read	PostgreSQL
1	429.4 events/s	10,311 MiB/s	88,465 IOPS	1,751 tx/s
2	443.6 events/s	10,296 MiB/s	91,313 IOPS	1,644 tx/s
3	442.0 events/s	10,371 MiB/s	91,410 IOPS	1,624 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 London 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.
SKU and region were matched to retained deployment records. A missing detected SKU uses the operator-supplied plan and remains 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.
