Even if we take different hardware into account we can readjust for measured vs theoretical throughput.

Ceph cluster achieves 1 TiB/s / 1.7 TiB/s = 0.58% of theoretical throughput.

3FS cluster achieves 6.6 TiB/s / 9 TiB/s = 0.73% of theoretical throughput.

That difference is still pronounced, yes. But the workload is so different. Training AI is hardly random read. Still not a comparison which should lead you to any conclusions.
