The Backend Runtime Showdown

See how Go, Rust, Bun, Node, Python, and PHP handle real-world checkout transactions under load.

Forget synthetic micro-benchmarks and hello-world scripts. This is a production-grade stress test measuring throughput, latency, and resource efficiency across actual e-commerce workflows.

What Is This Benchmark?

Most benchmarks test hello-world endpoints or simple JSON serialization. This one is different.

We simulate a real-world checkout transaction — the kind that generates revenue for online businesses. Each test measures how each runtime handles:

→ Throughput: How many successful checkouts per second under load
→ Latency: P50, P95, P99 response times across a 30-second ramp-up
→ Resource Efficiency: Memory, CPU, and database connection usage
→ Error Handling: Reliability under extreme load
