| Metric | Meaning |
| --- | --- |
| `ssh_true_ms` | Time to run `ssh host true` with the same key/options. |
| `dosh_attach_ms` | Time for `dosh-client --attach-only` to render the first frame and detach. |
| `dosh_attach_ms` | Time for `dosh-client --attach-only` to render the first frame and detach on the configured path. With `--no-cache`, this is cold SSH bootstrap plus UDP attach. |
| `dosh_cached_attach_ms` | Time for a warmed Dosh client to attach using cached UDP credentials/tickets, render the first frame, and detach. This is the fast-path claim and should be approximately network RTT plus local process/render overhead. |
| `mosh_start_true_ms` | Time for `mosh host -- true` to bootstrap, run `true`, and exit. |
These are not identical workloads. They are still useful because they measure the
startup path each tool must pay before useful remote work begins. Public numbers
must include the command, machine, OS, CPU, network path, and sample count.
Do not cite cold `dosh_attach_ms` as the core speed claim. Cold Dosh still pays SSH
startup/authentication. Cite `dosh_cached_attach_ms` for repeat attach/reconnect
speed, and cite cold `dosh_attach_ms` only to show that fallback remains competitive
with ordinary SSH.
