I have the same issue under Windows, and I've tried all other settings, but it's still not working. However, under the same network conditions, the SMB protocol can reach 900MB/s.

Here are my diagnostics, along with some screenshots of my settings. unraid-diagnostics-20230622-2316.zip

I've added a standalone NVMe solid-state drive to my NAS, which has a speed of 7GB/s. However, after connecting to iSCSI, the speed is still very slow. Here are my diagnostics, could you please help me figure out where the problem lies?

I'll try the whole disk (block device) for iSCSI later.

Regarding Diagnostics do you mean the screenshot, or the full Diagnostics.zip file downloaded from the Unraid system?

You mean instead of using FileIO, you want to use the Devices page to design the storage source? Here is my Diagnostics. iscsi-target.txt

This is the speed of my SMB protocol

I'm connecting to ISCSI on Unraid through my mac mini, my internal network is 10Gb, I also set write back in iscsi to true, but my hard drive speed is only 60MB/s. I can reach 940MB/s with SMB connection in the same network and hard drive environment, I've been troubleshooting all morning but I can't find out what the problem is, please! Please help me.
