----------
How to Confirm IP Issues Aren’t Affecting Performance
✅ 1. 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Outdated NIC Drivers: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).
