I usually think of the margin of error for Benchmark as about 10%. Any difference smaller than that is likely to be noise. This might also be a case where you move the code from place to place in the file and it changes speed (see No More Meaningless Benchmarks!).

Or maybe it's faster to say {$a<=>$b} rather than {$b<=>$a} for some reason. If I run your benchmark, changing only reverse sort to sort (so the 'reversed' case actually sorts forward), the results look about the same—{$a<=>$b} wins.

In any case, I'll probably keep thinking of them as "the same speed", benchmarks be damned.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
