SoftEther speed is 10% of max speed

Post by shakibamoshiri » Fri Jan 12, 2024 10:54 pm

Running some tests with "vpncmd /tools /cmd trafficserver/trafficclient" shows big differences between non-tunnel throughput with tunnel throughput.
- enable/disable "UDP acceleration" did not make any difference
- enable/disable "Encrypt VPN sessions" did not make any difference
- using 32 TCP connections in parallel did not make such a difference
- using SE tap interface or Linux veth interface did not make such a difference
- SeucreNAT never enabled
- no other application were using the bandwidth

Can someone tell why and where the bottlenecks are?

- does the ISP throttle tunnels ?
- does SE sever need a psychical machine and a dedicated NIC ?
- can bridging SE tap to NIC help ?

It is possible. Check client/server and SE/DE versions' speed entirely on a test LAN. Also apparently In latest version of SoftEther, SecureNAT is faster than tap in Linux.

I did lots of tests
All tests were run with Dev version
Also Client to Server tested , it was a little bit slower
These test were done using SE server to SE server via cascade connections
LAN testing is a good point, it was overlooked I will check LAN and SecureNAT (I noticed on GitHub there is a new release)

Here are tests on a stable ISP in which I am sure there is no throttling

### Testing Secure NAT (vNAT) ###
Since I am using two servers and they are connected via a split tunnel from
server A to server B. For testing vNAT, SecureNAT was enabled on Server B and
on Server A a tap interface added to a Linux namespace in order to isolate
server A speed test (client).

Here is a speed-test on the main namespace of server A (client)

NOTEs
- both servers A and B compiled the latest release https://github.com/SoftEtherVPN/SoftEth ... /5.02.5181
- both servers are Debian 11 from the same ISP
- both servers OS configurations are alike

But results are the same, speed is around 10% of max speed!
Now my question is that is this by design for FREE version of SE server ?
I mean if speed for a free version has been limited or no ?

It also possible that maybe I am doing them wrong!

It seems the official binaries have no limits but the published source code is indeed limited (in some aspects, not sure about speed). Which brings me to your "latest" 5181 build - I got 5345 half a year ago, and currently build 5369 is available here https://dev.azure.com/SoftEther-VPN/Sof ... _a=summary

 - both servers A and B compiled the latest release https://github.com/SoftEtherVPN/SoftEth ... /5.02.5181
...
Now my question is that is this by design for FREE version of SE server ?
I mean if speed for a free version has been limited or no ?
It seems the official binaries have no limits but the published source code is indeed limited (in some aspects, not sure about speed). Which brings me to your "latest" 5181 build - I got 5345 half a year ago, and currently build 5369 is available here https://dev.azure.com/SoftEther-VPN/Sof ... _a=summary

what do you mean by "official binary" ?
do mean stable version ? here
https://softether-download.com/files/so ... 8.31-tree/

several commits and changes tested (building from source) and result are the same.

Here is the last commit on master branch

Code: Select all

commit dc2b11918abe0566de69b7ae7bf5450cfbaa3b6d (HEAD -> master, tag: 5.02.5181, origin/master, origin/HEAD)
Merge: ff4b74af 7398bf27
Author: Ilya Shipitsin <chipitsine@gmail.com>
Date:   Sun Dec 3 14:08:34 2023 +0100

    Merge pull request #1933 from chipitsine/master
    
    CI: use OPENSSL_ROOT_DIR for cirrus-ci builds
you can see the commit message is "Merge pull request #1933 from chipitsine/master" and the same as the link you gave (the first one)
https://dev.azure.com/SoftEther-VPN/Sof ... _a=summary
#20231203.1 • Merge pull request #1933 from chipitsine/master

and the master is tagged to "5.02.5181" so how could you get "5369" a year ago ?

No, I wrote that 5369 is available now.

This lack of attention may be affecting your speed testing methodology. Please test it out on this server -> speed.softether.com:9821

My results indicate no VPN upload speed degradation whatsoever and 40% lower download speed due to the connections asymmetry and other overheads.

No, I wrote that 5369 is available now.
First of all this link https://dev.azure.com/SoftEther-VPN/Sof ... _artifacts has no artifacts I cannot see any file to download

This lack of attention may be affecting your speed testing methodology. Please test it out on this server -> speed.softether.com:9821
second this address is not available

This page isn’t workingspeed.softether.com sent an invalid response.
ERR_INVALID_HTTP_RESPONSE

Third how to test with speed.softether.com ?
My results indicate no VPN upload speed degradation whatsoever and 40% lower download speed due to the connections asymmetry and other overheads.
Did you test on 1G and 10G networks ?
On slow networks like 10M or 100M it is okay the overload is low, but I am testing on 1G and 10G networks

One more question what is the best test methodology?

Have a closer look AND click around. The original address again https://dev.azure.com/SoftEther-VPN/Sof ... _a=summary
how to test with speed.softether.com ?
vpncmd /tools /cmd TrafficClient speed.softether.com:9821

One that emulates real-life application:
- note TrafficClient from your VPN server to a speed server
- compare TrafficClient from a VPN client to the same speed server

I think I have gotten blinded , cannot see any release binary files
vpncmd /tools /cmd TrafficClient speed.softether.com:9821
This is measuring raw speed and I have no issue with this

VPN Tools>TrafficClient speed.softether.com:9821
TrafficClient command - Run Network Traffic Speed Test Tool in Client Mode
Starting the client program...

The issue is the speed over a tunnel not over the internet
One that emulates real-life application:
- note TrafficClient from your VPN server to a speed server
- compare TrafficClient from a VPN client to the same speed server
this is what I did , did you see my other posts ?
I used a Linux namespace to isolate it from main network
Anyway testing with a client is not that much hard I will do this as well

Yeah, it wasn't a real-life application test. You did this...
Ping from server A (client) to server B (server)... time=0.301 ms

cascade connections of 32 TCP
You had pushed that shared VPS to 100% CPU usage with multiple processes and several intra-connections. Since you can not test it directly from your [.ir] location and presumably don't control a separate VPS, I don't hold my breath for any conclusive result.
