<div>Lets say if "compression , Atime, ashift , dedup etc" all creating problem in VM then why they are not causing the same problem when copy from proxmox to OmniOS or OmniOS to proxmox?<br>

</div><div>but happy with results, though some minor gliches are there but i sucessfully copy 14GB data with 100 to 180mbps. it is not that good but better from my last experience. <br><br></div><div>now testing by connecting the storage directly to the server to avoid the latency issue.<br>
