# Public summary

The recorded lab produced approximately 1.98–2.03 Gbit/s VPC throughput, up to approximately 452 MiB/s sequential block-storage throughput, approximately 6994 read and 3006 write IOPS in the selected random test, and PostgreSQL results of approximately 10272 TPS at 32 clients and 9937 TPS at 64 clients. Average latency was 3.055 ms and 6.249 ms respectively; failed transactions were 0 in the recorded aggregate.

The result is useful as an engineering pre-study: increasing client concurrency coincided with slightly lower throughput and higher average latency in the recorded points. The available evidence does not prove CPU, load, queueing, or latency as one single root cause.

The lab is single-region, single-configuration, and short-duration. It is not a complete performance audit, a production SLA, or a guarantee for other regions or sizes. Evidence archive gaps remain.
