Benches - criterion benchmarks (#5)
* split crate into library and binary criterion can not benchmark binary crates * Add store benchmarks * Add more, not reproducible benchmarks The benchmarks are currently hardcoded to use a specific system on my computer. To run the tests yourself, change QUERY_DERIV__OLD in benches/common.rs In the future, I would like to pull a specific copy of the nixos sqlite db from e.g. a github repo to make the benchmarks reproducible * Do not hardcode system derivations to use in benchmars By default, the oldest system is compared to the current system A specific system can be specified using environment variables (see benches/common.rs)
