Free-threaded CPython removes the GIL, so CPU usage per process becomes the key indicator of real parallel hardware utilization in mod_wsgi benchmarks.

WSGISwitchInterval tunes CPython’s GIL handoff timing, enabling more predictable scheduling for CPU-bound WSGI workloads when guided by telemetry.

WSGIFreeThreading enables mod_wsgi to run with free-threaded CPython builds where no GIL exists, allowing parallel Python execution without interpreter locks.

mod_wsgi 6.0.0 adds opt-in per-interpreter GIL support via WSGIPerInterpreterGIL, enabling improved concurrency control for production WSGI deployments.
