Benchmark results

Metrics with a significant change:

• note_trial_decrypting_time_in_ms (8): 91.8 (+115%)

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.

Values are compared against data from master at commit 640c89a0 and shown if the difference exceeds 1%.

This looks reasonable to me.
