Measured 2026-05-07 to 2026-05-08 on Alpine edge, x86_64, 8 cores, 14 GB RAM.
PHP 8.5.6, opcache always on. Drupal 11.x-dev (7 455 vendor .php, 8 499 classes)
as the realistic single-threaded workload. A small C harness (8 pthreads ×
2 000 000 small mallocs) for the multi-threaded contention scenario.
