Latency Impact and How to Minimize?

Hi, I am curious on a x86_64 machine, if I run a tcpdump, how much latency will tcpudmp add (assuming that I can dedicate a core to tcpdump and OS won't reschedule it to another core)? And what's the best way/setup (besides avoiding using promiscuous mode) to minimize the latency impact to the packet delivery to the application? Besides using TAP/port mirroring... If protocol matters, let's say it is TCP. Thanks in advance.
