I apologize if this has been answered before. I didn't find it.
When you set max mss size in mangle, which size is set. Only payload size, or payload + TCP header size?
Yes, but not only that, I'm thinking of that, if you are doing QoS on traffic, then also IPSec encryption and decryption on that same traffic is processed by single core...Are you referring to the fact that queue tree on a CCR is processed by a single core.
