Nordvpn Slow Speed

Open VPN low speed. Troubleshooting ideas?

Nordvpn Slow Speed

I have done a NordVPN speed test. Is NordVPN really as slow as everyone claims? Any fast servers? NordVPN 20% Discount: https://vpnpioneer.com/out/nordvpnIn. I just picked up nordVPN and when I torrent a file with p2p servers its slow, like ridiculously slow. About 800 kb/s max across all types of files. I've tried different servers, disabled utp, 3 different clients. My normal internet is around 400-500mbps and torrents pre vpn (legit torrents) were about 15 mb/s average. Re: SLOW broadband through NordVPN ‎ 23:23 - edited ‎ 23:35 im not on M350 only M100,but with no VPN being used and just doing the speedtest i only get 51.92mb download speed,shouldnt i be getting very close to the 100mb thats advertised?? NordVPN does not apply any speed or bandwidth limits, but using a VPN in itself can sometimes decrease your internet speed to a certain degree.

Hello All!
STATS:
VPN DD WRT Router: Netgear R6700
Standard Router: Netgear R8000
ISP: Xfinity (Comcast)
PC: MSI GE72VR
VPN Service: NordVPN
Speed Test Service: Speedtest.net
Subscribed speed: 1000 MBPS D / 45 U
Observed Speed on R8000: 947 MBPS D / 45 MBPS U
Observed Speed on R6700 VPN Active: 15 MBPS D / 35 MBPS U
Observed speed on VPN PC Client: 900+ MBPS D / 38 MBPS U
VPN speed is simply too slow when the router is the client. I actually ran DD-WRT on the R8000, but the speeds were being limited to 340 MBPS *no vpn*. once I restored stock firmware, the speed went back to 900+ MBPS.
VPN support blames the router. I just want to confirm that on this thread.
We're talking about a serious amount of Bandwidth here, but the CPU utilization never jumps above 12% (VPN Support blamed CPU).
another interesting test, using the 'NordVPN APP' gives me similar speeds to that of the DD WRT router, but using Open VPN client on PC yields the 900+ MBPS.
Do you have any suggestions for improving this speed?
Thank you all for your assistance!!!!

DD-WRT Build: DD-WRT v3.0-r32170M kongac (06/11/17)
VPN Settings / Install guide used: https://nordvpn.com/tutorials/dd-wrt/openvpn-gui/
Log Attached. It seems I'm having a fair amount of errors, but the connection is still successful.
I do not have 1000 MBPS Upload. I have 45 MBPS Upload with 1000 MBPS Download.
Comcast won't give me the pleasure of that without paying twice as much... Gigabit pro is $300 a month.

oops meant download
And yes that does sound like an 'expensive priviledge' I'd thought they were still way back at 250 Mbs. Are you in one of their test areas?

Yes,
I am in one of the gigabit / Gigabit pro areas.... Unlike Google Fiber, its ridiculously expensive....
$150 a month for Gigabit, $300 a month for 2 gigabit.
but as always... Monopoly...

Instead of UDP try TCP on port 443.
I get 2x speed this way

On a R6700...
You should be able to get 25 Mbps with UDP
You may be able to squeeze a fee more Mbps depending om what server you specify (closest server physically to you is better)
You are 100% being limited by the router.
If you want faster VPN speeds you need a faster router.
A Linksys WRT3200ACM is what you need to get 100+ Mbps on the VPN
Trust me... I know my $417
P.S. --> Router Processors are not in the same class as PC's (x86) and they can only encrypt and decrypt so fast. Unfortunately... These router companies are focusing on other routing needs and not VPN speeds.
For Gigabit style encryption you would need to do a custom x86 ddwrt pc build and make your own router.

Absolutely right. Because of heavy encryption speed is proportional to the router's processing power.
I have tried everything to 'squeeze' as much out of my poor little WRT1900AC v1 as possible.
I spent several hours just on MTU adjustments alone.
If you don't want to change your current hardware setup, then it will be a matter of dialing it in to find what works best for your configuration.
Closest geographical server
DNS Servers
TCP / UDP
Less encryption (128 vs 256)
...are all adjustments you can try.
From what I've read about Nord VPN they are very particular about their settings so some of these may not be available to you.
*My download / upload speeds with OpenVPN Client enabled are generally: 34 Mbps / 20 Mbps

Thank you all for your insight!!
so it is confirmed that the Broadcom CPU (ARM?) simply can't achieve that high of throughput.
- TCP / UDP changes give a few more MBPS, but not enough
- NordVPN is very strict on which settings need to be used (Force 256). which is fine, I want good security.
- I am willing to spend some $$$ to get something worth while. a device that can handle Gigabit speeds won't be obsolete for at least a few years.
This causes me to evaluate the purpose of using the router, which is to provide a fast WIFI VPN in the home for Mobile devices and Roommates (not savvy enough to use it otherwise).
the best WIFI speed I have ever achieved is 270 MBPS
I think it would make the most sense to purchase a Hardware Firewall or device specifically made to achieve 300+ MBPS VPN throughput..... or maybe even build an X86 device to handle it as sploit suggested.
If you have any suggestions on brands or devices, I would be happy to hear them.
Thank you again for your expertise everyone!!!

There are quite a lot of articles questioning if that is true so I would put a huge question mark on it. Besides...what are you doing that you need 256 instead of 128 if I may be curious..

Interesting, I will investigate this further regarding forced settings.
As for my need of 256.... If I told you why, I wouldn't really need to be using 256.. would I?😁

Well that's unfortunately true, but I had to try
About the question mark, I was talking about 128vs256bits which is more secure.In NordVPN you won't be able to use 128, only in PIA that I know of.
