They are the same code underneath, but are initiated differently. 
join() is an operator, similar to '+' and '*' etc.  So it will be 
initiated MUCH quicker than a native method call (.join()) which has a 
method operator '.' followed by looking up the method, building the 
frame, then executing the native code.  The differences you are seeing 
are the differences between these two actions.  both are nominal, 
however.  The method-call syntax is highly useful when chaining 
something (foo.explode().join()).
