You are right cbporter, for very short times it is not precise enough. Also it can depend on the way compiler optimizes the code, I think. If one just needs to now if it takes 10ms or 100ms to send a packet, it is accurate enough Smile

IMHO the best way to achieve good resolution is usually to perform the task many times and measure total time, averaging it later - that is the way TIMING() does it. Using this trick you can get resolution in microseconds, assuming there is not too big deviation between the lengths of single actions.
