| I'm getting low throughput on macOS. How can I fix this? | May-26-22 |
| You may need to set a few parameters to enable higher performance at 10Gb/s.
1) Set the mode to full-duplex, which allows the adapter to send and receive at the same time.
To set full-duplex on macOS, go into the System Preferences->Network and select the Twin10G interfaces. Click the "Advanced..." button in the lower right. In the Advanced window select the "Hardware" tab and set "Configure:" to "Manually". Set duplex to "full-duplex".
2) If your entire network will support it, set packet size to jumbo frames which pack six times as many bytes per packet.
For a large frame to be transmitted intact from end to end, every component on the path must support that frame size. The switches, routers, and NICs from one end to the other must all support the same size of jumbo frame transmission for a successful jumbo frame communication session. Switches that don't support jumbo frames will drop jumbo frames. In the event that both ends agree to jumbo frame transmission, there still needs to be end-to-end support for jumbo frames, meaning all the switches and routers must be jumbo frame enabled. At Layer 2, not all gigabit switches support jumbo frames. Those that do will forward the jumbo frames. Those that don't will drop the frames. For a jumbo packet to pass through a router, both the ingress and egress interfaces must support the larger packet size. Otherwise, the packets will be dropped or fragmented. If the size of the data payload can't be negotiated (this is known as PMTUD, packet MTU discovery) due to firewalls, the data will be dropped with no warning, or "blackholed". And if the MTU isn't supported, the data will have to be fragmented to a supported size and retransmitted, reducing throughput.
To set Jumbo frames on macOS, go into the System Preferences->Network and select the Twin10G interfaces. Click the "Advanced..." button in the lower right. In the Advanced window select the "Hardware" tab and set "Configure:" to "Manually". Set MTU to "Custom" and enter "9000".
3) Not all devices support flow control, or the absence of flow control. If Flow Control is off, turn it on; if it is on, turn it off.
4) Update your macOS to at least 10.13.6. Earlier versions enable SMB signing by default, which can cripple 10Gb networks. Update your macOS, or disable SMB signing. (You can Google how to do this.)
5) If you're in a macOS server environment:
If your Server is running 10.13.6+ enable SMB protocol, and disable AFP protocol.
If your Server is running 10.12.6- enable AFP protocol, and disable SMB protocol.
If your Server is running 10.13.6+, update your clients to 10.13.6+ for a significant performance boost. |

| Upon connecting the Solo10G, I see an error message "Accessory Needs More Power" | May-13-22 |
| Your computer does not have 15W available that the Solo10G requires, but instead only 7.5W.
When plugging external devices into a MacBook Pro, the 15-inch and 13-inch models with four Thunderbolt 3 ports will provide 15W only to the first two devices and then 7.5W to the second two devices in the order that they are plugged in, irrespective of port and device type. The 13-inch model with only two Thunderbolt 3 ports will provide 15W to the first device and 7.5W to the second. Try disconnecting all the devices and plug in the Solo10G Thunderbolt 3 Adapter first.
Some PCs do not supply 15W to all of the Thunderbolt 3 ports. Check you computer specifications for details. Make sure the Solo10G is the first device plugged into the computer. |
