Hey!
I got the old Asus RT-AC88U just to use dd-wrt for the vpn in AP/repeater mode, as asus firmware doesn't support VPN in ap/repeater mode.
Everything is working fine, except it is extremely slow, about 50% to 80% slower from the original speed.
I am using the latest firmware as of today DD-WRT v3.0-r52095 std (03/23/23) with openvpn 2.6.1. the new openvpn 2.6.2 has been released, hope it will be added soon.
What I do believe:
It is not RT-AC88U CPU, as it is only 8-14% when full load.
It is not RT-AC88U RAM, as 83% of RAM is free upon testing.
It is not the client, as I am using OpenVPN on my PC and I am getting 100% of the speed.
It is not the server, on the contrary I am using one server in the router and it is located in my country, while in my PC it is double server and it is not located in my country and I am getting 100% of the speed.
Any idea?
I can accept 30% to 50% slower as I agree to compromise speed for privacy (although I think I should get 100% of the speed) , but 80% slower is too much.
Am I doing anything wrong, cause VPN in router are not that slow! _________________ Asus RT-AC88U Donations

I am using a vpn on my router and double vpn on my pc! it is like a tor connection!
The server I was using in my router is fast, but when connecting to the servers in my PC it will be slow.
I disabled the VPN in my PC, and tested the VPN in the router alone, it is much faster bu still not getting the full speed, I am getting about 90% of my original speed!
I changed the server in my router, and tested some servers, now I am getting much faster speed.
I guess if I test more I will get full speed eventually, but it is annoying changing the servers in the router. I am happy at 90% of my original speed with the current servers
For now, I am guessing it is just servers issue. I am happy with 90% of the speed using VPN on both my router and double VPN in my PC. _________________ Asus RT-AC88U Donations

You will (most likely) never see 100% of your ISP bandwidth using OpenVPN (or even WireGuard) simply because of the cryptography and hardware limitations. _________________ "The woods are lovely, dark and deep,

I can confirm, in my case it was the servers I was using!
Yesterday, after I change the server in the router it became very fast, but at night it became slow. I changed the server, and it is fast again.
Today I tried another VPN provider, and the results are odd!
In my router I am using provide X connecting to a server not in my country.
In my PC, I am using double VPN from another VPN provider.
And the results are strange using different providers on both PC and router.
The response time is so quick, almost as if I am not using a VPN at all.
I am watching youtube videos with no delay at all for buffering when opening videos. It opens very fast even 4k 60fps.
Internet speed tests give me very slow download and upload (very strange) and the ping time is higher although it is quicker.
Downloading files are slower, but it is acceptable.
The results vary from time to time, but the response time is very quick.
Not sure why using 2 VPN providers game me much faster reponse time. Maybe the servers? If I try more servers using my VPN provider I would get it too?
@egc I am gonna find a VPN provider with WireGuard I am sure it will be faster.
"And the results are strange using different providers on both PC and router"
If your referring to the vpn throughput (download speed), your PC VPN throughput will be a lot faster than running the same vpn on your router, your router only has a CPU clock speed of 1.4GHz Most 10+ year old pc will run 2.0GHz let alone newer more modern PC's with a lot faster clock speeds CPU's 3 - 5.0Ghz ish.
