# Benchmarks

These benchmarks compare high-level operations that power Viem across
versions and engine providers. Lower timings are better.

The following results are single-call durations from an Apple M4 Max running
macOS 26.5.2 and Node.js 25.9.0. The comparison represents Viem 3.0.0-next.2
with Ox 1.2.0 and Viem 2.55.10 with Ox 0.14.33. The fastest result in each
row is bold.
