## `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.
