🚀 Feature

Use multiple processes when extracting ImageNet training archive.

Motivation

I recently extracting the ImageNet training archive with the code of torchvision and was suprised how long it took. I realised that after extracting the main archive, we only extract the subarchives one after another:

Pitch

I think we can speed that up significantly by using multiple processes to do this simultaneously. IMO doing this would have no drawbacks.

Additional context

If we want this feature, I could take it up, albeit with a low priority.
