Benchmarks

Criterion suites measure the matching engine in isolation. They do not include TLS, network delivery or the durable server's synchronous journal writes.

cargo bench --locked -p me-bench --bench latency
cargo bench --locked -p me-bench --bench throughput
cargo bench --locked -p me-bench --bench e2e
cargo bench --locked -p me-bench --bench stress
cargo bench --locked -p me-bench --bench realistic

Record the Git revision, Rust version, CPU, operating system, compiler options and workload. Run on an otherwise idle machine with a consistent power policy. Criterion writes reports under target/criterion; compare repeated runs rather than a single best value.

me-datagen creates reproducible order streams with --seed. Inspect its options with cargo run --locked -p me-datagen -- --help. Record symbol count, order mix, book depth and seed with any results.

For service measurements, include transport, journal sync, client event application and restart/replay cost. Test both steady load and bursts on the intended filesystem. Report percentile latency, throughput, errors, memory and disk growth. No benchmark number in this repository is a deployment SLA.
