📝 Description

A comparison of PHP execution models, specifically focusing on the throughput limitations of PHP-FPM versus persistent worker solutions like RoadRunner. The segment outlines that the traditional PHP-FPM request lifecycle incurs a significant bootstrap overhead per request, which can limit performance, citing a throughput ceiling of approximately 400 Requests Per Second (RPS) on identical hardware. Solutions utilizing persistent workers, such as FrankenPHP and RoadRunner, demonstrate higher potential throughput, with RoadRunner achieving over 8,000 RPS by maintaining workers that load the application once rather than on every transaction.
