MY SITUATION:
It took me over 2Y before someone explained what DEDUPE does to performance..!
Obviously disabling dedupe does nothing for previously written data, it just stops deduping new data.
Obviously, I wanna grant my data a governor's pardon (via the ZFS Replication Task) -- to an array which is not & will NEVER be deduped.
THE QUESTION:
Please tell me this SOLVES the issue and doesn't just kick the DeDupe can down to the server I'm transferring it to..?
MY REASONING:

MY REASONING:
- I ask bc it's a BLOCK-LEVEL vs OBJECT-LEVEL copy task.
- Source LAN Adapters: 1 Type: SFP+ Link Speed: 10 Gb
- Target: LAN Adapters: 1 Type: SFP+ Link Speed: 10 Gb
- Communicating through an L2 SFP+ (10GbE) switch.
- The first 13 min -- the transfer rate was ~3GB/ min or ~42 MB/s
- After ~6 hours it's at 960 GB ... which is ≤ 46 MBps ...
- It should be faster, but, it IS copying a dataset that's probably 50% deduped.
- Which is part of why I want to confirm ... that this isn't just replicating the problem, also.
