ROCK64 as VPN Gateway
#11
Hi guys,

today I received my Rock64 and of course immediately set it up to do some tests. Openssl now performes way better as visible here:

Code:
You have chosen to measure elapsed time instead of user CPU time.

but openvpn performance is still slower than on Raspberry Pi4:

Rock64
Code:

[email protected]:~$ sudo time openvpn --test-crypto --secret /tmp/secret --verb 0 --tun-mtu 20000 --cipher aes-256-cbc

RPI4
Code:
[email protected]:/etc/openvpn $ sudo openvpn --genkey --secret /tmp/secret
[email protected]:/etc/openvpn $ sudo time openvpn --test-crypto --secret /tmp/secret --verb 0 --tun-mtu 20000 --cipher aes-256-cbc

0inputs+0outputs (0major+287minor)pagefaults 0swaps

As you can see the Raspberry takes 12,76s to perform the test, whereas the Rock64 needs 15,95s. Based on the explanation in this thread

https://airvpn.org/forums/topic/18322-ho...hroughput/

it means, that still the Rock64 is slower. Is openvpn taking advantage of the hardware acceleration of Rock64? Any other explanation?

Thanks!

are you running aarch64 userland? and is your openvpn built to use armv8 crypto extensions?
Come have a chat in the Pine A64 IRC channel >>

Hi @xalius ,

I am using Ayufan's Debian Minimal which should be aarch64. I have not rebuild openvpn as I was assuming that it is not necessary. Do you know what settings need to be changed when building openvpn to enable these extensions?

Thanks!

Hi all,

the problem might be that openvpn is using different libraries than openssl:

       /lib/ld-linux-aarch64.so.1 (0x0000007f9b0a8000)

OpenVPN is using libssl.so 1.0.2 and OpenSSL is using libssl.so 1.1, can this be an issue? Anybody knows how to make OpenVPN using the hardware crypto modules of Rock64?

Thanks!

Hi guys,

good news, the problem seems to be Debian Stretch. I have installed Armbian based on Buster and now the timing is far below RPI:

Code:
[email protected]:~# openvpn --genkey --secret /tmp/secret
[email protected]:~# time openvpn --test-crypto --secret /tmp/secret --verb 0 --tun-mtu 20000 --cipher aes-256-cbc
Wed Dec  4 21:23:21 2019 disabling NCP mode (--ncp-disable) because not in P2MP client or server mode

real    0m4.937s
user    0m4.891s
sys     0m0.046s

This means, in theory, that the Rock64 is able to process 600 Mbit/s. That is what I was expecting. So for everybody who needs performance with OpenVPN, use Debian Buster (with OpenSSL 1.1).

Hi all,

now all the tests run just fine but I am only able to get a speed of approx. 24 MBit/s when transferring large files. With my RPI I reach 64 MBit/s (for same URL). One reason could be that the Rock64 is using "only" 25% of a CPU core when a large download is started (via CURL), while the RPI is using one core with 100%. Configuration changes with "nice" are not making any difference. Also I have not found any other parameter that could help here. Any idea?

Thanks!

Hi guys,

I am facing big issues in using the Rock64. I have installed Ubuntu 18.04 Bionic minimal 64bit (arm64) Image [microSD / eMMC Boot] [0.8.3] image from this page:

https://wiki.pine64.org/index.php/ROCK64...5B0.8.3.5D

After boot (serial console connected) I have executed "sudo apt-get update" and "sudo apt-get upgrade" and suddenly during the process I face kernel panics as seen below:

Code:
sudo apt-get update
....
sudo apt-get upgrade

I have tried that a few times (installing the image and then update) but every time a kernel panic appears (not always the same). Is this a known issue? I have a Rock64 Rev. 2. I already replaced the device as I thought it might be a hardware issue, but with the new one same problem occurs.

Any hints what is going wrong?

Thanks!

I always suggest using https://www.armbian.com/rock64/ It's definitely the gold standard as far as the Rock64 is concerned.

Yes, I have tried this distribution also. The issue here is that the main purpose for me buying the Rock64 was OpenVPN performance. Although the tests mentioned in this thread run fine the throughput is much lower than with Ubuntu Bionic (Armbian approx. 3MByte/s, Ubuntu approx. 8,4MByte/s). I was not able to figure out where the difference is. On Armbian the OpenVPN process is somehow only using 25% of CPU, on Ubuntu it is more than 50%. Is there a general limitation of CPU utilization on Armbian? Is there a way to change that?

Thanks!
