Hello,
I am using log4j to help me record the execution times of several functions (1
to n) using code similar to the following snippet:
logger.debug("Timestamp before...");
function_n();
logger.debug("Timestamp after...");
For most of the functions I get execution time of 0ms. This is despite the fact
that these functions are quite different from one another. The remaining few
functions have execution time of 15 or 16ms. This is also despite the fact that
these functions are also quite different from one another.
So my questions are:
1. what exactly is the precision of the timestamps generated by Log4j?
I am using Win XP and am aware that each timer tick is recorded every 15.625
milliseconds (http://www.lochan.org/2005/keith-cl/useful/win32time.html).
2. Is there a way I can improve the precision of the timestamps in my Java
program?
Any feedback will be appreciated
Sana
