AirVPN / slow usenet issue

[derfelo 0]

Hi! I'm new to VPN's and am currently trying AirVPN. I'm impressed so far except for one issue - my usenet speeds are super slow. As speedtest results below show I'm actually close to maxing my connection through AirVPN, browsing is very snappy and normal downloads, torrents etc. all get good speeds. But usenet is super slow and actually cripples the whole connection when it's running even at it's incredibly slow speed:

 

Speedtest without VPN = 36.27 Mbps / 9.54 Mbps

Speedtest on VPN = 34.55 Mbps / 9.06 Mbps

 

Usenet without VPN = ~4.2 MB/s

Usenet on VPN = ~200 KB/s

 

Speedtest on VPN with usenet downloading @ 200 KB/s = 2.15 Mbps / 0.25 Mbps

 

I've researched the forums here and have so far tried the following with no improvement:

Tried various AirVPN servers (I'm based in UK, have tried various UK/NL/BE servers)

Changed TCP/UDP buffers to 256KB

Changed drivers for "TAP-Windows Adapter V9"

Tried 2 different usenet providers and their various available SSL ports.

Tried both Eddie client & OpenVPN client.

 

Set-up: Windows 7, Sabnzbd usenet client.

 

I was thinking it might be the usenet providers identifying and limiting a VPN user, but that would not explain the whole connection being crippled when it's downloading. Am I missing something obvious? Any help or suggestions welcome!

Were you able to identify the issue?  I am facing the same thing, though it only started happening in August.

Windows 7 OS

Sabnzbd v2.2.1

airVPN v2.12.4

 

Have the same problem, very slow speeds on Usenet with airVPN enabled, fast speeds return when I disable the VPN ?
