So, you want to time a piece of code using a high-resolution timer on the x86 architecture. Okay, great! You can now time the execution of codes that run in sub-microsecond range! In this post, I’ll go into details on how to do things properly and what to watch out for. I’ve pulled together different resources so that we can cover the intricacies and minutia involved in using this hardware timer properly. ...
