# Oj::Parser is significanly faster (~1.3x) on the next 3 micro-benchmarks in large part because its
# cache is persisted across calls. That's not something we can do with the current API, we'd
# need to expose a stateful API as well, but that's no really desirable.
# Other than that we're faster than regular `Oj.load` by a good margin (between 1.3x and 2.4x).
