I'm trying to see how much delay a packet typically suffers in the FreeBSD tcp/ip stack. This is what I thought of doing: trace the path of data flow from the place a socket write call is made to the place where the data is actually passed on to the network interface; place calls to microtime() at these locations and see the time difference between them. Could anyone point out potential problems with this approach? Any better alternatives? I'm rather new to this kind of thing and would appreciate some feedback.
