Hi, I’m having some issue with the speed of download using openvpn, the upload on my server side is 35Mo/s so it’s not a bandwith issue. Here is my config: - server side: i have a Hp proliant Gen 8 installed with OMV and openvpn as a pluggin. Server is connected to my internet box with ethernet (i have the right speed via eternet from my PC to my server for example) - client side: iphone/ipad with openvpn app. Some test i have made: - i have tested my real upload speed using gdrive by uploading a file directly from my PC, i had 35Mo/s - i have tested the bandwith from my phone directly on my network, i have 15Mo/s, the bottleneck is the wifi. - i have tested a feature of my box that let me share files that are on internet box (i dont know the protocol behind that), i have 7Mo/s from my phone using 4G (i think the max speed then) So as you can see i have «high » speed on all my tests and i know where the bottleneck is. However when i m trying to download from my server outside my network via my iphone on 4G i’m only at 2Mo/s (not enough to see hd movies in streaming). I have read some threads about the config but i’m not sure if modified the config file as i should since nothing really happened... Please help me enjoy my server content everywhere 😁

What is your ISP advertised speed .. try http://speedof.me

I’m using usenet so much more reliable that internet speed test, coupled to gdrive and it gives me the right figures. Up: 35Mo/s, Down: 60Mo/s

Maybe something here will help: https://community.openvpn.net/openvpn/wiki/Gigabit_Networks_Linux

Inalready read that but i’m not sure how the config works in ios, should i modify only .conf file or rather the .openvpn? Same in OMV putting paramaters in the box on OMV interface is enough?

All I can tell you is that openvpn does not throttle .. it will run exactly as fast as it can on what ever you run it on. Edit: Provided you have setup your network and openvpn correctly.

I have tried your link but nothing works for me... I have done some more extensive test with iperf3 that confirms all my bandwidth: -Server - PC in Ethernet without OpenVpn : 930Mbps -Server - IOS in wifi without OpenVpn : 185Mbps (bottleneck Wifi ac) -Server - PC in Ethernet with OpenVpn : 920Mbps (i'm not sure to understand this the bottle neck should be the UP from my ISP no?) -Server - IOS in wifi with OpenVpn : 170Mps (same remark as above, however it would be the DOWN from my mobile ISP in this case since my UP from my home ISP is higher than my DOWN mobile ISP) -Server - IOS in 4G with OpenVpn : 8Mbps So I have two question: 1/ From my above test, when i use OpenVPn shouldn't i be limited by my UP from my IPS even if i'm in Wifi? 2/ Issue seems focused on my IOS device, i have use the same .opvpn config file on both my PC and my IOS, what magical option should i use on IOS?

My config on my clients: [code]client remote IP 1194 proto udp dev tun remote-cert-tls server comp-lzo cipher AES-256-CBC ;auth-user-pass persist-key persist-tun nobind resolv-retry infinite verb 3 mute 10[/code]

to follow up on my issue, i have been using FTP protocol instead of SMB to download/stream my videos, it seems i have gained 1MB/s, while it's not huge, now the stream doesnt have any lag! So i'm half happy. I have also compare SMB and FTP speed on this config: Server - IOS in wifi: FTP is 30.5MB/s while SMB only 17MB/s! FTP protocol seems to max out my wifi (ac)! Now i'm still trying to figuring out how i could achieve this performance over my VPN... @Admin, could you transfer my post to the IOS section? thank you.

Nope. Like i said, speedtest on 4G is 60MB/s...

Slow download from server using openvpn

I tried the Sydney hosted test file first and in chrome, it said the speeds I was getting was 1.2 MB/s to 1.3 MB/s consistently, I usually don't get above 1 MB/s downloading off a local server from Steam. When I tried other location test files, the speeds were less than 1 MB/s.

Wrong thread?

1. Use UDP
2. Turn compression back on
3. If you care about security, turn encryption back on. It doesn't have that much overhead, really.
4. Set your tunnel MTU to 8192 (add "tun-mtu 8192" to your client config)
5. Add the following 2 lines to your client config file:
fragment 0 mssfix 0
6. Run speedtest-cli on your droplet to see what speeds you get there.
7. Try your speed test again.

Try this on your server and then client: https://speedtestfast.com
