Benchmarks

These folders follow scriptc's benchmarks/. scriptc times a compiled binary against Node. pyscriptc times a compiled binary against CPython, which is the island for code that does not lower.

scriptc	pyscriptc	What runs today
benchmarks/runtime	benchmarks/runtime	one kernel per lowered module, plus the original integer, float, and string loops. import_module and asyncio.run have no timed call. fenced-strip stays a fence
benchmarks/scaling	benchmarks/scaling	the original loops across sizes. scriptc's array, collection, regex, and async probes need types this subset does not lower
benchmarks/builds	benchmarks/builds	catalog only. log-summary and inventory-report are multi-module programs
	benchmarks/baseline	reference time and peak RSS. The kernel geomean is the original four loops. stdlib, scripting, and island have their own geomeans
	benchmarks/adoption	which outside test suites can be compiled, and the fences that keep them on CPython
	benchmarks/native	a C ABI .so linked from the small runtime, and the same work through a PyInit_* extension on the island
	benchmarks/compat	frozen language, builtin, stdlib, and top-100 denominators. python -m benchmarks.compat.score writes a snapshot. python -m benchmarks.compat.delta compares two snapshots
	benchmarks/net	the network receipt: loopback HTTP client, compiled against CPython, and sustained http.server throughput with p50/p99. Opt-in, no baseline gate
	benchmarks/library	the library receipt: a pure-Python PyPI package (certifi) resolved through the deps lane, compiled from the unpacked wheel, output diffed against CPython. Opt-in, no baseline gate

A row is timed only after its stdout matches CPython. A call outside the lowered subset, or any syntax outside gates-v1, is a fence: the runner records it and does not emit a time.
