## `cuprate-benchmark`
|
||||
This crate links all benchmarks together into a single binary that can be run as: `cuprate-benchmark`.
|
||||
|
||||
`cuprate-benchmark` will run all enabled benchmarks sequentially and print data at the end.
|
||||
|
||||
## Benchmarks
|
||||
Benchmarks are opt-in and enabled via features.
|
||||
|
||||
| Feature | Enables which benchmark crate? |
|
||||
|----------|--------------------------------|
|
||||
| example | cuprate-benchmark-example |
|
||||
| database | cuprate-benchmark-database |
|
||||
|
||||
## Features
|
||||
These are features that aren't for enabling benchmarks, but rather for other things.
|
||||
|
||||
Since `cuprate-benchmark` is built right before it is ran,
|
||||
these features almost act like command line arguments.
|
||||
|
||||
| Features | Does what |
|
||||
|----------|-----------|
|
||||
| json | Prints JSON timings instead of a markdown table
|
||||
| trace | Use the `trace` log-level
|
||||
| debug | Use the `debug` log-level
|
||||
| warn | Use the `warn` log-level
|
||||
| info | Use the `info` log-level (default)
|
||||
| error | Use the `error` log-level

## `cuprate-benchmark-lib`
|
||||
This crate is the glue between
|
||||
[`cuprate-benchmark`](https://github.com/Cuprate/cuprate/tree/benches/benches/benchmark/bin)
|
||||
and all the benchmark crates.
|
||||
|
||||
It defines the [`crate::Benchmark`] trait, which is the behavior of all benchmarks.
|
||||
|
||||
See the [`cuprate-benchmark-example`](https://github.com/Cuprate/cuprate/tree/benches/benches/benchmark/example)
|
||||
crate to see an example implementation of this trait.
|
||||
|
||||
After implementing this trait, a few steps must
|
||||
be done such that the `cuprate-benchmark` binary
|
||||
can actually run your benchmark crate; see the
|
||||
[`Benchmarking` section in the Architecture book](https://architecture.cuprate.org/benchmarking/intro.html)
|
||||
to see how to do this.

## `cuprate-criterion-example`
|
||||
An example of using Criterion for benchmarking Cuprate crates.
|
||||
|
||||
Consider copy+pasting this crate to use as a base when creating new Criterion benchmark crates.
|
||||
|
||||
## `src/`
|
||||
Benchmark crates have a `benches/` ran by `cargo bench`, but they are also crates themselves,
|
||||
as in, they have a `src` folder that `benches/` can pull code from.
|
||||
|
||||
The `src` directories in these benchmarking crates are usually filled with
|
||||
helper functions, types, etc, that are used repeatedly in the benchmarks.
|
||||
|
||||
## `benches/`
|
||||
These are the actual benchmarks ran by `cargo bench`.
