[Convert Cache RAID1 to RAID10]

I have found no difference with raid 10 and raid 1 with my 4 ssds. 

[Slow transfer speeds over 10Gb network to an NVME drive]

You are doing better than me! Im getting 300mb windows to unraid and about 400mb unraid to windows. I also setup a p2p connection to bypass the switch and nothing changed.

I still haven't solved my issue either. Transferring from an nvme drive to 2 samsung 850 pro ssds in raid 0. Iperf3 shows bandwidth around 3gbit. MTU 9014 is enabled on both sides.

They should be more than fast enough. I had 3 850 evos for cache that gave me around 700 MB/s transfer speed. I assume you have jumbo files enabled on both as well as the switch. 

I have not been able to enable jumbo frames on unraid. NIC supports jumbo frames but the kernel refuses any mtu over 1500. The same NIC on windows works fine with jumbo frames and the NIC description shows support for Linux. I'm not too sure if that's the issue because I've heard other people saturating 10gbe without jumbo frames enabled.

Changing the docker apps to mnt/cache/appdata fixed my docker issue.  Thanks for the tip Greg.  I am also now getting up to 1.15 GB/s transfer speed!!!! What type of drive are you writing too/from Greg? anything but a multidrive ssd raid or a very high speed NVME drive will be the bottleneck over a 10gbe network.

I currently have 4 Samsung 850 pro ssds in btrfs raid 10. That should equal around 1100mb read/write. I am getting 350mb max over the network.

I am having the same issues here. Can't saturate 10gbe at about 350mb/s. Direct I/O is giving me call traces and all docker apps had to be changed from mnt/usr/appdata to mnt/cache/appdata for them to be able to read/write. To top it off i am still only getting 350mb over 10gbe! I am out of ideas.

Why don't you use the GUI? It has the possibility to set the MTU size and changes made this way willl stick after a reboot.

I changed the mtu in the gui and rebooted however the dashboard still shows eth0 mtu as 1500 even though the gui setting is grayed out at 9000 now.

[Enable Jumbo Frames]

I recently bought 2 asus XG-C100C 10gbe nic's one for unRaid and one for the client. It supports jumbo frames 9kb which I was able to enable on the windows client machine. The problem is on the unRaid machine. When I run "ifconfig eth0 mtu 9000" to test it out I get "SIOCSIFMTU: Invalid argument". I am currently running 6.4.0-rc8q.
