What is measured
Equivalent xorshift64* integer mixing, the same iteration count and a verified checksum. Runtime uses warm-ups and repeated wall-clock samples.
Measured, reproducible, qualified
Honest performance results
No universal “fastest” claim. These numbers cover one deterministic integer workload on one machine and publish the commands and raw samples.
Run csp-bench to generate results.

What it does not prove
This does not represent web servers, allocation, concurrency, GPU work, compilation at scale, or every computer. C+ currently uses a C++ backend, so close C+/C++ runtime is expected.
