Test With iperf (Raw Network Speed) Run iperf3 to check the actual network (not SMB/NFS overhead): 🔵 On NAS (as server): bash Copy Edit iperf3 -s 🔵 On PC (as client): bash Copy Edit iperf3 -c NAS_IP -P 4 -i 1 Expected Results for 10GbE: 9.5 Gbps (~1.1 GB/s) = Good ✅ 3 Gbps (~300MB/s) = Problem with network ❌ ---------- Multiple Network Interfaces (Incorrect Interface Used) If your PC or NAS has multiple network connections (e.g., 1GbE and 10GbE), your system might be using the slower 1GbE link instead of 10GbE. 🔍 Check active network routes (on Windows): powershell Copy Edit Get-NetRoute | Sort-Object DestinationPrefix 🔍 On Linux/QNAP: bash Copy Edit ip route ✔ Solution: Set the 10GbE interface with the lowest metric (higher priority). Windows: powershell Copy Edit Set-NetIPInterface -InterfaceAlias "10GbE-NIC" -InterfaceMetric 1 Linux: bash Copy Edit sudo ip route add 192.168.1.0/24 dev eth1 metric 10 ---------- Network Adapter Driver & Settings Update Method Outdated NIC Drivers: Make sure you have the latest firmware and drivers for your 10GbE NIC. Intel, Mellanox, and Broadcom NICs benefit from updated drivers. Windows RSS (Receive Side Scaling) Disabled: RSS allows network traffic to be processed across multiple CPU cores. Enable it via PowerShell: powershell Copy Edit Set-NetAdapterRss -Name "YourAdapterName" -Enabled $true Energy-Efficient Ethernet (EEE) Enabled: This power-saving feature can throttle network speeds. Disable it in the NIC settings (Device Manager - Advanced - Energy-Efficient Ethernet - Off). ---------- TCP Window Scaling / Network Stack Issues Windows Auto-Tuning Level: If incorrectly set, Windows might throttle TCP performance. Check with: powershell Copy Edit netsh int tcp show global If "Receive Window Auto-Tuning Level" is disabled, enable it: powershell Copy Edit netsh int tcp set global autotuninglevel=normal Interrupt Moderation: If enabled, the NIC groups packets together, which can reduce throughput. Try disabling it (Device Manager - Advanced - Interrupt Moderation - Off). ---------- NASCompares Free Advice Area - https://nascompares.com/contact-us/ This description contains links to Amazon.
