Those times are way too small to be reliable. You're down at the level where OS 
scheduler effects are significant.

Make the test longer, say between 1 and 10 seconds. That should give you more 
trustworthy numbers.

(Running the test too long is also counterproductive: the OS is likely to slow 
your process to save power or decrease heat.)
