PHP 8.5 Memory Efficiency: How Much RAM Do You Really Need? (2026)

by

When optimizing PHP applications, we obsess over RPS, P99 latency, and JIT performance — but one metric is equally important for production costs: memory efficiency. In the cloud, you pay for RAM. The question isn’t just “how fast” but “how much throughput per GB of memory.” We benchmarked PHP-FPM, Swoole, and RoadRunner — all configured … Read more

How CPU & Memory Limits Impact PHP Performance in Docker (2026)

by

TL;DR: In I/O-bound PHP applications, reducing Docker CPU by 87% (from 4 to 0.5 vCPU) and memory by 96% (from 8 GB to 256 MB) has zero measurable impact on RPS. All configurations delivered 93–94 RPS under 50ms database latency. The bottleneck is external (database wait time), not internal (CPU or memory). Running PHP in … Read more
