CPython 3.12.3 /usr/bin/python3.12, Ubuntu 3.12.3-1ubuntu0.17, ordinary GIL build; Linux 5.10.134-013.16.kangaroo.al8.x86_64 x86_64 glibc 2.39 GCC 13.3.0.
Input 'One two one', four word_count tasks/sample, cpu_work 20000 iterations per task, one warmup and five samples per mode (sequential/thread/process/asyncio). Repeated modes run consecutively, not randomized or isolated from host noise; process runner submits/awaits each worker serially, threads 2 workers and 2 backlog; asyncio CPU loop has no await. Scope includes store, executor creation, execution, result checks and shutdown; subprocess CPU time excluded from parent process_time_ns. cProfile runs once after all unprofiled samples on sequential path only.
No direct third-party runtime dependencies. Node isolated Hexo v22.16.0.
