10 users. Ten different tasks.

Measured result

10 simultaneous initial requests; 10/10 HTTP workflows completed and 10/10 workspaces persisted. Batch wall time 74.65 seconds. Health checks: 14, failures: 0.

This supports 10 mixed light workloads in this one short run. It does not establish 10 heavy builds or 10 simultaneous Docker previews, sustained capacity, or a production SLA.

Resource measurements

VPS: 4 CPU cores, about 7.75 GiB RAM. Existing workloads were left running. Samples are periodic, so may miss brief spikes. API health latency includes network/proxy time.

Scope and limitations

Ten dedicated synthetic Forge QA identities used real authenticated public endpoints and the configured server LLM. Google/email signup and actual browser login were not load tested. No customer accounts were used. Seven static website/edit tasks, one Node app, one chat and one plan were launched together. Builds may ask brief questions; the harness answered the offered options. Static websites were checked in local Chromium using the exact returned files. This is a finite smoke/load test, not an endurance test.

The current source limits Node previews to two active and one building. Therefore this result cannot be advertised as ten Docker previews. The Node example has no external dependencies and does not cover large React/Next installs. Initial preflight had a QA harness revision conflict; corrected before model requests. No production limits or code were changed.
