Detailed results

All benchmarks are run on txs on the `Benchmarking` contract on the repository. Each tx consists of a batch call to `create_note` and `increment_balance`, which guarantees that each tx has a private call, a nested private call, a public call, and a nested public call, as well as an emitted private note, an unencrypted log, and public storage read and write. This benchmark source data is available in JSON format on S3 [here](https://aztec-ci-artifacts.s3.us-east-2.amazonaws.com/benchmarks-v1/pulls/7260.json). ### Proof generation Each column represents the number of threads used in proof generation. | Metric | 1 threads | 4 threads | 16 threads | 32 threads | 64 threads | | -
