Profile( true )
In this form Profile turns the profiling on. Subsequent computations
will record the time spent by each function and the number of times each
function was called. Old profiling information is cleared.
Profile( false )
In this form Profile turns the profiling off again. Recorded
information is still kept, so you can display it even after turning the
profiling off.
Profile()
In this form Profile displays the collected information in the
following format.

The last column contains the name of the function. The first column contains the number of times each function was called. The second column contains the time spent in this function. The third column contains the percentage of the total time spent in this function. The fourth column contains the time per call, i.e., the quotient of the second by the first number. The fifth column contains the time spent in this function and all other functions called, directly or indirectly, by this function.
