I ran this a few times. There was some variance, but I thought it would be fun to add to the list. I had to update the test to run benchmarks. Looks like TryFrom is used for bytes -> Share now. This will likely change the benchmark results a little bit.

WARNING: HTML report generation will become a non-default optional feature in Criterion.rs 0.4.0.
This feature is being moved to cargo-criterion (https://github.com/bheisler/cargo-criterion) and will be optional in a future version of Criterion.rs. To silence this warning, either switch to cargo-criterion or enable the 'html_reports' feature in your Cargo.toml.
