# Run benches

```

cd erasure-coding # ensure you are in the right directory

cargo bench

## `scaling_with_validators`
|
|
|
|
This benchmark evaluates the performance of constructing the chunks and the erasure root from PoV and
|
|
reconstructing the PoV from chunks (either from systematic chunks or regular chunks).
|
|
You can see the results of running this bench on 5950x below (only including recovery from regular chunks).
|
|
Interestingly, with `10_000` chunks (validators) its slower than with `50_000` for both construction
|
|
and reconstruction.

Results from running on an Apple M2 Pro, systematic recovery is generally 40 times faster than
|
|
regular recovery, achieving 1 Gib/s.
