Very poor Speed test

NethServer Version: 7.x
Module: your_module

Hi… Long time no see :slight_smile:
I’ve got some trouble with NS7.x Speed test. It’s very slow
My Internet package is 1000/500 Mbps. I’d tested via notebook behind Router is nearly seems to be.
But With NS7 Diagnostic speed very low see my picture

My Hardware is

Serve around 50 Client

Could someone guide me what should be the problem?

Thanks in advance.
Cheers

Hi @i_combo

I’m sorry to hear about the slow speed test results on your NethServer. To help diagnose this, I need to better understand your network setup:

Please confirm these details:

  1. Network topology:
  • Is your WAN connection (ISP → modem) connected directly to NethServer (e.g., enp2s0 = WAN, another interface = LAN)?
  • Or does it go through an external router first (e.g., ISP → Router → NethServer)?
  1. Interface speeds:
  • Run these commands on your NethServer:

ethtool enp2s0 | grep -E “Speed|Duplex” # Check WAN interface speed/duplex ip link show # Show status of ALL interfaces

  • Does enp2s0 show 1000Mb/s (1 Gbps) and full duplex?
    • If using multiple interfaces (bonding/LAG), share your config.
  1. NethServer roles:
  • Is it acting as your primary firewall/router (using Firewall, Traffic Shaping, etc.)?
  • Or is it just a backend server (e.g., mail/files) behind another router?

Potential quick checks:

  • Interface bottleneck: If enp2s0 negotiates at 100Mbps (not 1Gbps), this would limit speeds.
  • Duplex mismatch: Half-duplex settings cause collisions/performance drops.
  • Bandwidth saturation: Your 50 clients might be consuming bandwidth during tests.
  • QoS/Shaping: Check if traffic policies limit download bandwidth.

Install iftop if missing (real-time traffic monitor):

sudo dnf install -y iftop

Monitor WAN traffic during speedtest:

sudo iftop -i enp2s0

Watch for: Unusual spikes/processes saturating download bandwidth.

Testing Path

  1. Where did you run the speed test?
  • did you test from a client PC behind NethServer (e.g., laptop → NS → ISP)?
    → If yes, what speeds did you get via Speedtest.net / Fast.com on that client?

Physical Path Confirmation

Is your actual data flow:

Please share these details, and we’ll dig deeper! Cheers.

Hello @jgjimenezs Thanks for your advice. That’s help me the way to ride on :slight_smile:

Before I confirm your details. Today I found weak point of e1000e (ENO1)

e1000e eno1 Reset adapter unexpectedly

Then I do clean install NS7.

Here is NS port 980 speed test result

I also make speedtest .net from Win Client behind Green (Local)
Downloading is nearly 900 Mbps
Uploading is nearly 500 Mbps

something miscalculate!! I think :slight_smile:

For me It’s good enough to use as it is.

Cheers

excellent, I hope you are well. Take care of yourself.

same with “new” server-manager, cockpit (:9090)?
searching for the network card model e1000e on this community you might find similar problems.
