Hi there, hoping someone can help me understand what more I can do to improve my replication speeds between two TrueNAS-Scale machines (VM's hosted on Proxmox servers). I am able to get acceptable iperf3 results between the two sides but my replication speeds top out around 2Gbps according to both Unifi and the TrueNAS network reports. The replication job is set to SSH+Netcat and no encryption is used.
The hosts are DL380e G8 servers with 2xE5-2430 and 32GB of ram. Each TrueNas has the an lsi 9208i passed through to it with 12 HDD attached. Sender is setup as 6xmirrored vdevs and the receiver is 1x12 raid2z vdev. Any help that can be given on other things that I can try to improve upon this or suggestions on what I can do to find where the bottleneck is greatly appreciated.
