I saw this last night with .1354. I went to .380.1681 and it went away.
Sorry, I meant that the CPU 2 has no load.
The soft irqs are probably from network IO and the mechanism most commonly used by drivers is to service the irq and delegate the work to a soft irq handler. These handlers are guaranteed to run on the same cpu that queued them to prevent ordering problems and simplify locking. So you should expect to see a single CPU getting hit.
That's by kernel design of the soft irq handler mechanism.
I don't know about which CPU irqs are delivered, maybe only one of the CPUs, but that's possibly hardware design specific, don't know.
So there might not be much that can be done about that.
From my observation on the broadcom contaminated kernel, I think you're correct. The issue of this thread is perhaps less interesting. Might be simply some user space apps hogging on core 0...
You brought up one interesting point. I wonder for IPSec.. can the encryption/encapsulation be done asynchronously on core 1 while packet flow process still handled by core 0?
one question, because speak with askey, askey is Asus computer. They do the software and manufacturin the new router of Movistar, they do the software specific of Movistar, and resolved moré problems. I have the latest firmware mitrastar and comtrend is two of the routers that puts Movistar today, are you interested?Hi all,
Thanks for your help, we have found some issues about ISP Movistar triple vlan setting.
1. CPU loading issue
2. VPN issue
3. qos vs. IPTV issue
4. others
We have fixed some bugs and will check with Movistar about some setting for users. Thanks you guys a lot!
Thanks,

Hi rubencc33,one question, because speak with askey, askey is Asus computer. They do the software and manufacturin the new router of Movistar, they do the software specific of Movistar, and resolved moré problems. I have the latest firmware mitrastar and comtrend is two of the routers that puts Movistar today, are you interested?
as you said you have to talk to Movistar, topic of what profiles, but we wondered if you wanted the firmware than routers Movistar, if you served for help with something, and if askey is the new manufacturer delos Home Gateway unit MovistarHi rubencc33,
They do the software and manufacturin the new router of Movistar. => Really? I don't know about that, this case isn't my task, I shouldn't interrupt even if I am interested.
Thanks,

I imagine you'll have to talk to Movistar, I mean that I have in my possession the firmware two routers Movistar being installed was only if you wanted or your partner so they were sent around, my english is a bit bad and I have not been able to explain, sorry and thank you very muchHi Rubencc33,
Thanks for your kind suggestion, if any issue, we will contact with Movistar directly by ASUS (won't via Askey). Actually, we always keep contacting with Movistar (the contact window isn't me.), you don't worry about anything. As I said, this case is my colleague's, I don't want to interrupt, I think my colleague will handle that.
Thanks,
Vanic
Yes, I am having it another time. Core 2 is not being used.I am having this issue. Reached out to OP.
The networking stack and hardware drivers are single threaded, so they can't use both CPU cores.
He's referring to the networking code that is part of the router's Linux kernel. Any traffic that is entirely processed by this code will be limited by the power of the router's CPU. To achieve maximum throughput the router needs to have "hardware acceleration" enabled which bypasses the normal network stack and uses proprietary features of the Broadcom chipset.Sorry can you explain a little better? "network stack" ?
I was told this router could reach 940mbps but its hitting 99% core usage on core 1
