### Comparison

Sequential requests from a single client against a local Node.js HTTP/2 server (1 KiB JSON body, keep-alive), best of 11 runs of 2000 requests, pinned to one core. Profile counts are the distinct versioned impersonation targets exposed by the public API. Numbers are indicative — rerun them on your own hardware before drawing conclusions.

[^1]: `primp` accepts arbitrary version strings and snaps to the nearest shipped profile, so the set is not enumerable through the public API.
[^2]: Over HTTP/1.1 — with HTTP/2 enabled the server closes the session with `GOAWAY` after roughly a thousand requests.
[^3]: Cipher suite and signature algorithm order only; no control over extension order, GREASE, or HTTP/2 `SETTINGS`.
