You can always run routeros on X86 hardware. I think the problem with things like mangle rules run into. Had loss and a hell of a lot of reorders at just 500mbit through a CCR1036 the other week, disabled 100 or so mangle rules and it vanished, but from looking at other routers I think it's more of a limit in the linux kernel (perhaps just the 2.6 one). Maybe routeros7.1 will be better, something to test in the coming weeks. 10/25 feels like a CCR2004? Or are you just talking switching. If routing remember it isn't full bandwidth - the 170gbit of ports is squished into 2x25 before hitting the CPU[0]. Not sure how much is offloaded to the PIPE.

> 10/25 feels like a CCR2004? Or are you just talking switching. That’s exactly right. Thanks for the tip that things get squished into 2x25gbit before reaching the CPU; this effectively means that anything that isn’t offloaded to the hardware is limited by “just” 2x25GBit. Is my understanding also correct that this would be the case for when traffic needs to go from the SFP+ ports to the SFP28 ones? Regardless, what I really wanted to do (mostly as an experiment) is use QoS to prioritize iSCSI and others; the problem I’m running into is that the CPUs are just not able to do that that fast. I think the only solution to this problem would be to use an x86 machine with a bunch of Mellanox cards in it.
