Klyn benchmark

Performance samples

Each Python / Klyn / C++ trio is executed three times. The displayed values are average wall-clock process times. The C++ column uses an executable compiled with g++ -O3 -std=c++20 -o <name> <name>.cpp.

* Klyn --clean removes the local cache before each execution. This column measures the worst startup scenario: rebuilding generated objects and then running the script. The Klyn column measures the normal cached startup path.

The benchmark source files are included in the Klyn distribution under samples/perf for curious users who want to inspect, run, or adapt them.
