See how Go, Rust, Rails, Node, Python, and PHP handle real-world checkout transactions under load.
Forget synthetic micro-benchmarks and hello-world scripts. The baseline numbers below come from a 500-iteration isolated load test (10k requests, 20 concurrent threads per backend). The Run Test tab lets you fire a live demo run from your browser — results will differ since requests route through the web server.
Requests per second under load
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:
Validate JWT session
Atomic DB update
HTTPS to payment processor
Write to database
Trigger async events
