When an eth port reaches full wirespeed, CPU reaches %100 traffic.
Profile shows Managment.
No fix in v6.10 too.
Mikrotik please fix this issue !
Anyone ?
what routerboard you have?
CCR 1036 v6.10.
Have you running firewall rules
No. Con Tracking off.

When a single interface reaches max wire speed, CPU tops out (managment) !
If you use bandtidth test on the same routerboard is that normal.
This is not bwtest. This is user traffic ! No bandwidnth test !
Mikrotik ?
Have you firewall rules running?
Ore block p2p connections?
There is NO conn tracking + NO NAT + No firewall + NO queue
Just PLAIN SIMPLE STATIC ROUTING+ ECMP
Thats it.
It is clearly a bug.
Yes i think is a bug
Make suppout.rif and sent this to support@mikrotik.com
Hopefully they help you further
I’m having issues pushing more that 1Gbs through my 10Gbs SFP on these boxes… Strangely I can push 10G of UDP traffic…
Maybe SNMP? Try to disable it… Try too disable the LCD Display. If it dont work, reboot Router with slower CPU Speed.
I think this is about flow control on the interface or maybe about interface queues (hardware queue)
Mikrotik has to check the reason.
