Benchmark results and methodology comparing Tenki runners against GitHub-hosted runners across real open-source build workloads.



Tenki runners run on modern bare-metal hardware, so the same workflows finish faster than on the older VM instances GitHub Actions uses. Because the per-minute rate is lower too, moving to a larger runner often speeds up a build while still costing less. The numbers below compare identical workflows on Tenki and GitHub-hosted runners.

How we benchmarked [#how-we-benchmarked]

* Tenki runner: `tenki-standard-medium-4c-8g` (4 vCPU, 8 GB RAM, bare-metal x64 Linux, one ephemeral microVM per job).
* GitHub baseline: `ubuntu-latest` (2 vCPU, 7 GB RAM, GitHub-hosted Linux).
* Workflow parity: identical YAML on both sides, with only the `runs-on` value changed. No caching plugins, prebuilt images, or custom action substitutions.
* Cache state: warm. Each workload ran three consecutive times per runner, and the third run is reported.
* Sample size: 3 runs per workload per runner. The numbers below are the median of the warm-cache runs.
* Workloads: real, reproducible builds from public open-source projects (Rust, Docker, Node.js, Go, Android, n8n).
* Date range: April 2026, re-run quarterly.

Results vs GitHub-hosted runners [#results-vs-github-hosted-runners]

| Workload                | GitHub-hosted | Tenki   | Delta      |
| ----------------------- | ------------- | ------- | ---------- |
| Rust `cargo build`      | 5s            | 3s      | 40% faster |
| Docker build            | 27s           | 19s     | 30% faster |
| Node.js `npm install`   | 10s           | 8s      | 20% faster |
| Go build                | 11s           | 0.1s    | 99% faster |
| Android `assembleDebug` | 1m 38s        | 1m 2s   | 37% faster |
| n8n monorepo (full CI)  | 55m 58s       | 29m 15s | 48% faster |

Cost [#cost]

On common CI workloads Tenki runs the same jobs up to 60% cheaper than GitHub-hosted runners, billed per minute with no startup surcharge. See [the pricing page](https://tenki.cloud/pricing) for the full rate card across vCPU, memory, and macOS profiles.
