My router board is ccr1036-12g-4s and it has very simple configuration. 200 pppoe user, firewall rule 66, interface traffic 300Mbps and around 250 queues but its cpu uses is almost 100% every time. While checking profile i found queuing is occupying the cpu. if i disable the connection tracking or enable fasttrack then everything is fine but i cant do so. any suggestion? and i have only 2 mangle rule(download and upload) for bypass of youtube.
