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:
Matthew Wright, Ryan Cassidy, Michael Zbyszynski, Audio and Gesture Latency Measurements on Linux and OSX, Proceedings of ICMC 2004, Miami
or just connect ãudio input to audio output of the soundcard and take a measure with some patch magics.
