Criterion benchmarks for Tonic

Running the benchmarks

From the root Tonic directory, cargo bench

After running, the reports can be found in tonic/target/criterion/report/index.html

Gnuplot is required for graph generation. If gnuplot is not installed, Criterion will display: Gnuplot not found, disabling plotting at the console.

Notes

1. Currently, these benchmarks only test the performance of constructing Tonic Requests and Responses, not over-the-wire throughput.
2. The thrpt value generated by Criterion is simply a measure of bytes consumed by the target function.
3. As we are not testing tonic-build compile time, the tests reference pre-compiled .rs files in 'benchmarks/compiled_protos'.
4. The original proto files are in the proto directory for reference.
5. This used the Criterion 3.0 Criterion Group functionality. Details here: https://docs.rs/criterion/0.3.0/criterion/

Interpreting Results

Criterion is particularly useful for establishing a first-run baseline and then comparing after code-changes - e.g. Performance has regressed below.

                        Performance has regressed.
Found 3 outliers among 100 measurements (3.00%)
  1 (1.00%) high mild
