FORKS? POOLS? ASYNC? Solving Wordle with Python’s concurrency tools
summary
Builds a Python Wordle solver/statistics bot and measures real performance: uses concurrent.futures with thread pools (no GIL win), process pool speedup ~4.8x by moving scoring into separate processes, and chunking to reduce IPC. Benchmarks: single-thread ~185s for first guess, process pool ~38s, random solver ~90% success, exhaustive solver hits ~96% (hard mode lower, plurals removed boosts to ~97.5%). Experiments with nogil show promise but currently nogil currently ~1.6x slower on threaded workloads; code and datasets (Wordle, Wordlebot, answer list) are exercised end to end.
