Compare/benchmark objstorage backends
The idea is to have an idea on how backends perform relatively to each other, in term of:
- volume efficiency (Mb used on disk per Mb of content),
- write performances (objs/s and Mb/s for one producer)
- write concurrency (how many concurrent workers can write in the objstore)
- read performances (random access),
- read concurrency
