Parquet has benchmarks below:

parquet-bloom-filter-benchmark
parquet-arrow-reader-writer-benchmark
parquet-column-reader-benchmark
parquet-page-index-benchmark
parquet-level-conversion-benchmark
parquet-encoding-benchmark
parquet-column-io-benchmark

Seems all benchmark has at least one of items/s or bytes/s metric

Thanks for going over this. If it's desirable to add more benchmark metadata still, feel free to post a PR, otherwise this issue should be closed.
