## Performance
How fast is BuntDB?
Here are some example [benchmarks](https://github.com/tidwall/raft-boltdb#benchmarks) when comparing BuntDB to BoltDB using a Raft Store implementation.
You can also run the standard Go benchmark tool from the project root directory:
```
go test --bench=.
```
### BuntDB-Benchmark
There's a [custom utility](https://github.com/tidwall/buntdb-benchmark) that was created specifically for benchmarking BuntDB.
*These are the results from running the benchmarks on a MacBook Pro 15" 2.8 GHz Intel Core i7:*
```
$ buntdb-benchmark -q
