I am living in China and as a foreigner it is essential for me to have free access to the internet.
I am having several servers in Europe, which have a quite good speed to China. Because pure VPN connections getting blocked quite fast, I am using a Shadowsocks with v2ray plugin on each server.
Here in China I am connecting to these servers through an OpenWrt installation on an Zyxel Armor Z2. I bought this router, because before I was running shadowsocks on a Glinet Travel Router and on an AVM Fritzbox. But the performance was not very good. The Zyxel Router has a dual core 1.7 GHz CPU and enough memory, so I thought handling shadowsocks will be easy.
But maximum download rate is about 60 Mbit/seconds, connected to shadowsock. It's not too bad, but I found out that the connection can be much faster.
I installed OpenWrt in a virtual machine on my homeserver (ASRock C2750D4I) and I was able to double the speed (up to 120 Mbit/s).
I don't understand, why I only get 60 Mbit on the Zyxel, but I also don't want to let OpenWrt run on my server all the time.
Is there any router or device you can suggest, which is maybe more powerful than the Zyxel and I can give it a try to install OpenWrt on it with shadowsocks and get a similar result as in the VM on my server?
I was thinking about to buy a x86 mini computer to let OpenWrt run on it. But most are with J1900 or N2600 CPU, which are quite old and I am not sure, if they are really better than the Zyxel.
Thanks frollic. Just installed irqbalance and put /usr/sbin/irqbalance in /etc/rc.local
Then I restarted the box. But unfortunately no improvement.
Do you think an RPi with OpenWrt would be more powerful? Or any idea of another powerful machine? Otherwise I think about to buy a mini PC, but with i3 CPU. That should be sufficient.
Yes... That was stupid. I saw the per code load, but I forgot to include it in the screenshot.
Anyway... I didn't have enough hope that the situation will improve with the Zyxel, so I bought a small embedded computer with an i3 CPU and 6 LAN ports.
Of course totally oversized for OpenWrt. So I installed vSphere as an Hypervisor and let OpenWrt run as a VM. So I still can use the device for other VMs later on.
And now it's working very well. Shadowsocks with v2ray-plugin can get up to 200 Mbit/sec. That's more than expected. CPU load is reaching about 10 % now.
