In this particular case, the setup they have is absurd and is only there as a tech demo. They are actually using 2 DPUs, one talking to the NVME SSDs and exposing them as iSCSI targets and the second one acting as as iSCSI initiator and then running ZFS on top of that. That's an insane amount of overhead and moving parts that can go wrong (the recommendation is to connect your storage devices to ZFS directly so it becomes aware of storage device errors as early as possible) so no surprise they didn't benchmark it.
