I'm currently trying to investigate this a bit. One of our user's home
directories is extremely slow to 'zfs send'. It started yesterday
afternoon at about 1600+0200 and is still running and has only copied
less than 50% of the whole tree:

On the receiving side zfs get tells me:

atlashome/BACKUP/XXX  used           193G                   -
atlashome/BACKUP/XXX  available      17.2T                  -
atlashome/BACKUP/XXX  referenced     193G                   -
atlashome/BACKUP/XXX  compressratio  1.81x                  -

So close 350 GB are transferred and about 500 GB to go.

More later.

Carsten
