Debugging my new network, when 10 Gigabit Ethernet Runs at 300 Megabits
TL;DR
A home network setup featuring 10 Gigabit Ethernet experienced unexpectedly low file transfer speeds of 300 Megabits per second. Despite confirming all components were operating at 10 Gigabit, performance issues persisted, prompting further investigation.
✦ Why It Matters
Investigate network configurations and hardware settings if experiencing unexpected file transfer speeds.
Key Takeaways
- Isolate components when troubleshooting network issues.
- Increase NIC receive buffer sizes to prevent packet loss.
- Disable Large Send Offload if experiencing low throughput.
- Use iperf3 to test raw network performance independently.
How It Works
The network performance issue stemmed from the NIC's default settings, which limited its ability to handle incoming packets efficiently. By increasing the receive buffer size, the NIC could accommodate more data, reducing packet loss.
Disabling LSO allowed for better handling of TCP segments, resulting in significantly improved throughput.
