# Benchmarks

This directory contains some micro-benchmarks that can help objectively
establish the performance implications of a change, and also benchmarks that
test the performance of different datastores using both the library and the SDK

## Manual usage

### Common

Execute the following command at the top level of the repository:

```console
$ cargo make bench
```

### Specific datastore
Execute the following commands at the top level of the repository:

* Memory datastore using the lib or the SDK
```console
$ cargo make bench-lib-mem
$ cargo make bench-sdk-mem
```

* RocksDB datastore using the lib or the SDK
```console
$ cargo make bench-lib-rocksdb
$ cargo make bench-sdk-rocksdb
```

* WebSocket remote server using the SDK
    * Start SurrealDB server
    ```
    $ cargo make build
    $ ./target/release/surreal start
    ```
    * Run the benchmarks
    ```console
    $ cargo make bench-sdk-ws
    ```


## Profiling

Some of the benchmarks support CPU profiling:

```console
cargo make bench --profile-time=5
```

Once complete, check the `target/criterion/**/profile/flamegraph.svg` files.
