Comment:

 There are quite a few situations in which the time can legitimately vary
 between evaluations. For example,

 {{{
 > x = big_expensive_computation
 > f x
 <slow answer>
 > f x
 <fast answer, because x has already been evaluated>
 }}}

 If you can point out a specific example where you think the times should
 be similar but they are not, you can reopen this ticket with more details.
