Performance Benchmarks

Benchmarks run nightly on 10K transaction ledgers. View workflow →

Benchmark details

What's measured:

• Validation: Parse ledger + validate (balance assertions, account opens, etc.)
• Balance Report: Parse + compute all account balances

Memory efficiency: rustledger typically uses 3-5x less memory than Python beancount thanks to Rust's zero-cost abstractions and efficient data structures.

Run locally:

# Quick comparison (requires nix)
nix develop .#bench
./scripts/bench.sh

# Criterion micro-benchmarks
cargo bench -p rustledger-core
cargo bench -p rustledger-parser
