Or two actual subnets on the one physical network? If it's two subnets on the same network, it should be sending an ICMP redirect back for each packet that comes via the router, which would certainly be maxxing a few CPU's?

Hmmm
No
Iperf at 3G udp
All 36 CPU's are up around 96-100%
It's a hairpin route in and out the same interface .... not sure if that's the problem...

I think I have found my problem.
This is a replacement CCR1036-8G-2S+ 6.33.3
I replace the config with a config from a previous ccr.
All the mac's are not the default ones. I am presuming that's causing all the packets to hit the CPU's
My other CCR sitting next to it, same config (diff ip's) same package.
Will advise when I get a chance to reset it

Hey Alex,
It should be fine, but can you provide an example of your test config and the routers software version? Is the test single or multi-threaded, tcp or udp?

36 cpu doing ~100% (97-98%) load and irq ... feels like somethings wrong there.

Hi
I'm testing switches again and doing a comparison to the CCR.
For some reason I can't seem to get past 1Gb/s without losses on my ccr1036.
Now this could be my VM's as VM to VM I can only get around 2-3Gb/s before iperf starts complaining ..
How are other people's experience with the CCR's I know about the 1Gb/s tcp stream limit, but I hand heard of any issues with UDP.
Infact I was pretty sure I had push it up to 9.8Gb/s.. but that was a while ago
