Benchmarks

This is where we keep benchmarks to various io-engine operations, example: how long does it take to create a nexus.

Prerequisites

It's recommended to run the benchmarks from this folder because:

1. we have a cargo runner to run it as root (required by the in-binary benchmark)

2. we have code in the cargo runner to chown the results to $USER and copy them back and forth from the io-engine-bench/results/criterion location and the cargo target location.

Examples

To run the benchmark in release:

RUST_LOG=disable cargo bench -p io-engine-bench

To run the benchmark in debug:

RUST_LOG=disable $RUST_NIGHTLY_PATH/bin/cargo bench -p io-engine-bench --profile=dev

Results

The criterion results are placed in the cargo target folder. You may direct your browser to this location to inspect the results.

For "persistence", if the path io-engine-bench/results/ exists, the benchmarks are moved to that location.
