Even at CPU parity, or even with modest N x CPU performance for single digit N, same ballpark. The expected performance once you load up the number of BGPSEC sessions, add on churn, etc., is a lot worse. And, my little laptop was basically idle, not doing all the other work that a router CPU needs to do.
