# Promigence benchmarks

A figure here carries the date it was produced and how it was produced. 

## Measured
- **104 ms**, cold start of an empty sandbox _(measured, 2026-09-14)_. Per tier: 104 ms small, 127 ms medium, 142 ms large.
- **39 ms**, warm fork on the box _(measured, 2026-09-14)_. One at a time 39.4 ms, a hundred at once 121.6 ms, two hundred at once 177.3 ms with all 200 served. Measured on the server itself rather than over the network.
- **987 ms**, first copy on a server that has never held it _(measured, 2026-09-14)_. The first copy of a 12.94 GB environment on a server that had not held it before.
- **12 → 100**, how far one provider's burst moved in 12 days _(measured, 2026-09-16)_. An independent public burst test: time-to-init, 100 concurrent, 120 s timeout. Not our measurement; read from its published raw results.
- **207 ms**, end to end, through the CLI _(measured, 2026-09-13)_. 207 ms from the US east, 204 ms from the US west, 209 ms from Europe, all p50 as the client saw it. Measured 2026-09-13 through the path a customer uses: the promigence CLI, over the network, an 8 vCPU / 8 GiB sandbox, from clients in three regions.
- **108,929**, forks in six hours, zero failures _(measured, 2026-09-14)_. 5.99 h, p50 43 ms at the first hour and 43 ms at the last, slope −0.09 ms/hour. Measured on the server itself rather than over the network.
- **177 ms**, at 200 concurrent, all served _(measured, 2026-09-14)_. 200 at once, every one served on the first attempt, 0 retries. A thousand in waves of a hundred holds the same: p50 99 ms, p99 165 ms. Measured on the server itself rather than over the network.
