Here is the data path that this slug took, this was at 8:30PM PST (source and destination IP's have been removed) Both ends are publicly numbered servers no NAT or anything else in between: The first is a back-and-forth FTP transfer of a 10B compressed data slug. The proprietary VPN protocol of theirs is not where the speed gain is coming from.įor your interest here is a back of the envelope speed comparisons of OpenVPN and not OpenVPN: In answer to your question the reason that ExpressVPN's firmware is faster is because it's using the wolfSSL library, and that library has explicit support for hardware encryption in the ARM CPUs. If the router is used with Wifi enabled a realistic throughput of about 30 Mb/s for OpenVPN with older CBC ciphers is about what you can expect. Other thing to try (but most likely will not get you anything or can even make it worse) is setting the tun-mtu value from 1500 to 1400 and leaving Tunnel-UDP-fragment blank and mssfix disabled. If you want to stay with standard OpenVPN research if they support a more efficient cipher like AES-256-GCM or Chacha-Poly (that is what they are using for Lightway)įurthermore if you use the latest build (as of now 46690 but probably wait for the one which will come any day) you can enable CTF+FA (On Setup page) this is a hardware acceleration which in itself does not speed up VPN but the router has some more CPU cycles available so it might eke out a few Mb/s more. How to install that app on your router is something you have to ask their support people If you want to stay with ExpressVPN that is your best bet for some more speed than standard OpenVPN. They have there own Lightway protocol which you can use via their app: I just checked with ExpressVPN and they do not support WireGuard. When I replaced with DD WRT (various builds) on the same router, I get 20mbps max over wifi and wired.įrom your comment, should I accept this is the best speed I can expect?Īlso, please would you be so kind as to link me to a post on how to get started with Wireguard on my R7000p? I installed ExpressVPN firmware on this router to test and I would get speeds upward of 60mbps. I have read many of your posts and learnt a lot from them so I am very honoured that you have taken the time to reply to me. Last edited by egc on Tue 15:00 edited 1 time in totalįirstly, thank you for your reply. I will move this post to the Advanced Networking Forum as it can be of interest to us all With my R6400v2 which has a comparable CPU I get 80 Mb/s running WireGuard to my VPN provider (Keepsolid) Most VPN providers support WireGuard today although not all on the router. If you want faster get a better router or use WireGuard which usually almost triples the performance. I think with optimal settings (Chacha-Poly, no compression and router doing nothing else (so no Wifi) the most you can get is 40 Mb/s so in practice around 30 Mb/s is what you can expect. The R7000P is dual core arm A9 1 GHz if I am not mistaken. "On the Express firmware I get 70-85mbps" I'm hoping the veteran users in this forum can please provide some guidance. I am my wit's end and don't know what else I can try. I am currently on 45767 build but have tried the most recent as well as others that were recommended by kernelpanic and egc I even tried msoengineer's post but it did not help with the speeds.Ĥ. I have read the Basic and Advanced Wifi settings and tried them but `not seen any improvement in speed. I have used nvram erase & reboot and reconfigured but no differenceģ. I have installed multiple versions of BS firmware for the R7000p and all of them give me the same issueĢ. I set up ExpressVpn and cannot replicate the speeds I get on the same router with the Express firmware involved. I purchased a Netgear R7000p and installed DD-WRT on it from factory firmware. Hello All, Long time reader, first time poster. Posted: Tue 14:32 Post subject: ExpressVPN on DD-WRT (NetgearR7000p) incredibly slow speeds
