# Runs and store TiKV benchmarks in a format that can be used by
# [cargo-benchcmp] and [critcmp].
#
# [cargo-benchcmp]: https://github.com/BurntSushi/cargo-benchcmp
# [critcmp]: https://github.com/BurntSushi/critcmp
#
# From your cargo project directory:
#
# bench-cmp.sh $before-commit $after-commit
#
# It will modify your git workspace, so make sure it's committed and
# clean.
#
# For #[bench] benchmarks, this script will save the output
# in .txt files in the current directory. For criterion benchmarks,
# it will save "baselines" in the `target` directory.
#
# Run bench-cmp.sh afterward to get a comparison report.
