  1. While troubleshooting slow transfer speeds, I ran an iperf3 test on my server and computer. What surprised me is that I'm not coming anywhere close to reaching 10gbps. As you can see from the screenshot, the closest I've ever gotten was 6gbps. I've tested two different PCIe network cards (one RJ45, one fiber) and an external Thunderbolt 2 NIC with pretty much the same or worse results. No matter what combination of setups I try, I cannot seem to break 6-6.5gbps. Any suggestions of what I should do? Here is what I'm using: Dell PowerEdge R710 10G SFP+ PCIe fiber card Sonnet Thunderbolt 2 10GB NIC Trendnet 10GB RJ45 PCIe NIC I've tried bypassing my Netgear switch (direct from Trendnet to Sonnet) with no change. I've also tried using only PCIe cards with worse results. Unraid to Windows, Unraid to macOS, you name it, no change. The fastest setup I've tried is using the fiber card on the server, going through the switch, to my MacBook Pro using the Thunderbolt adapter. Worst config was using the RJ45 NIC in a Windows computer, reaching a max of 3gbps. I'm at a loss right now for what the issue might be and would appreciate any advice.
  2. I'm sure this comes up a lot, but I've tried various things and nothing seems to help with my issues. I recently setup a new Unraid server and I'm not getting the read/write speeds expected. Writing to the server gets around 275mb/s where reading is up to 450mb/s. Here is a list of my hardware: Dell PowerEdge R710 SAS 6/IR 2 2TB Seagate Barracuda drives 500GB Samsung 970 Evo Plus in a PCIe 2.0 x8 slot (set as cache) 10GB SFP+ card Netgear XS708E switch Sonnet 10GB Thunderbolt 2 external NIC I've done a few performance tweaks to the settings with little to no difference: Jumbo frames on server set to 9000 Direct IO set to "yes" Reconstruct write enabled I've tested the Sonnet adapter on both Mac and Windows. I changed the jumbo frames on there as well to 9000. My Netgear switch is managed, but there's no option for setting the jumbo frames values. From what I can tell, it just passes whatever through. I'm not sure if this is a limitation of my hardware or not, but I'd appreciate any help you could provide.
