Unable to find server with acceptable speed

Recommended Posts

Hello,

 

I have tried multiple servers in Chicago, Phoenix, Atlanta, Dallas and Miami and cant seem to get more than 40Kb/sec  download (sometimes my upload is actually beating my download) out of any attempt. 

 

I am using openvpn on a linksys wrt3200acm running openwrt.

 

 

root@WRT3200ACM:/etc/openvpn# uname -a
Linux WRT3200ACM 4.14.90 #0 SMP Sun Dec 30 19:33:49 2018 armv7l GNU/Linux

root@WRT3200ACM:/etc/openvpn# openvpn --version
OpenVPN 2.4.6 arm-openwrt-linux-gnu [sSL (mbed TLS)] [LZO] [LZ4] [EPOLL] [MH/PKTINFO] [AEAD]
library versions: mbed TLS 2.14.1, LZO 2.10

here is the relevant section of my config file:

 

client
dev tun3
remote 64.42.179.34 443
resolv-retry infinite
persist-key
persist-tun
auth-nocache
route-delay 5
verb 3
explicit-exit-notify 5
remote-cert-tls server
cipher AES-256-CBC
comp-lzo yes
proto udp
sndbuf 524288
rcvbuf 524288
key-direction 1
(security/cert info follows but snipped)

I have a somewhat unique situation in that I have multiple VPNs set up going to other private routers, and need a bunch of ports forwarded for gaming, plex media server and a couple other more esoteric applications.  So you may notice that some of my options in the config file are a bit non standard such as naming the tun interface specifically and binding to it.  This is required for everything to work as it should.  This is the 4th VPN provider I am testing on and the 1st that I have no issues with my configuration, I have been able to set up everything as needed and all my applications work perfectly which is awesome.  All of the servers are connecting fine, and I do not see anything unusual in the log files regarding the connection, it all looks great except for the nasty dog breath speed.

 

 I have a Gigabit connection to the internet and my speed tests without VPN typically measure 960ish Mb/s download and 40Mb/s upload.  

Other things were running that I didn't want to stop while I took this test, so it isn't full speed.

Obviously I don't expect gigabit speeds out of the VPN, but I need to see at least 150Mb/s for this solution to be workable for me, and from what I see in other posts it looks as though that should be possible.

 

Any pointers to get me a bit more juice would be greatly appreciated.  Thank you for taking the time to assist.

 

Kind Regards,

 

David

i get full speeds from a processor slower than that one.   it may be a limitation of your OS on the router

 

have your tried lzo compression no?       that is turned OFF on all the servers per Staff

Hello Air4141841,

 

Any option that is disabled on the server is simply updated by the client to follow suit.  I turned it on to see if any of them would allow it, and if it had an impact.

 

Excerpt during negotiation of the channel:

While I certainly agree it may well be something with my configuration, that isn't it.  I also evaluated IPVanish, ExpressVPN and TrustZone where these speed issues did not exist, they were unfortunately all found lacking in some other area, but the speeds with them were OK.

 

Processor power is OK as well.

root@WRT3200ACM:/etc/openvpn# uptime
 07:28:29 up  5:38,  load average: 0.01, 0.01, 0.00

Thank you very much for taking the time to reply.

 

Kind Regards,

 

David
