Feature Request Replicate with Compression

[cpzengel]

Hi Guys,

perhaps you are able to add a kind of compression to the Replication, similar FreeNAS does it.

Perhaps you can Pipe the zfs send and recive via a gzip or lz4?

We do not use compression on Datasets and ZVOLs because of using VMs and latency!

This would multiply the load of Data, especially on WAN Connections.

For local Speedup perhaps you can add mbuffer?

I really appreciate your great work!
If there is a way to donate, let me know!

added -C to SSH
but please add compression with bzip2
testet with about 3x faster

/sbin/zfs send -pv -i rpool/data/vm-100-disk-1@zfs-auto-snap_daily-2019-05-24-1626 -R rpool/data/vm-100-disk-1@zfs-auto-snap_daily-2019-06-03-1626| bzip2 -c | ssh hh_repl@xxx.dyndns.org "bzcat| /sbin/zfs recv -dvF xx_repl“
