> A shared resource provides a way to build a real counting thread with a negligible overhead compared to a message passing approach. This already raised concerns with respect to the creation of a high-resolution clock [19]. In this method, one worker continuously increments the value of the buffer without checking for any events on the event queue. The main thread simply reads the current value from the shared buffer and uses it as a high-resolution timestamp.
