Thanks for your quick reply, it is hard to believe Redhat's Fedora DS has such problem on their OS. I tried to reduce bind_timelimit from 3 to 1 and it almost reduced the delay to an acceptable(but still noticeable) level, I think we will do this if there is no side effect to have such a small bind_timelimit. In the meaning time, I will stick to my taking-primary-IP workaround which reduces the delay to zero.
