Methodology

• All tests use the same hardware and Docker resource limits
• wrk runs from the host machine against the Docker container
• Each test runs for 30 seconds after a warm-up period
• Folk uses 4 forked worker processes
• Swoole, RoadRunner, and FrankenPHP use their default recommended configurations with 4 workers
