I wonder how many subvolumes were involved. It took a bit (2 or 3 seconds) longer when I had a lot of ZFS filesystems to mount (maybe between 50 to 100, I guess now) It was on 2 TeraByte max so smaller as the reported overall size.

I believe that the default x-systemd.timeout is 90 seconds. Should be more then enough I think. mount -a works much faster.

One of the Fujitsu developers responded with:
