I have measured such things precisely when the application required it. Its also fairly trivial to "hear" the latency by clapping into a microphone and monitoring it over headphones after it passes through the system. A 10msec difference is quite audible.
A general method for latency measurement of any system is described in this paper:

Apple puts good audio hardware in their laptops. I can get 14ms of latency on Mac OS X with Pd without really trying (I just set it to 14ms). I can get down to 11ms if I don't mind clicks when I operate the menus and switch to other applications.
as always when it comes to latency and people tell numbers, i have to ask my question: have you measured this? how? or was it just "putting a number somewhere and assuming that it's the real latency"? how much load do your settings allow?
