I did write the code for all three languages and I did run them. I didn't post the code because 1) the poster was correct about the timing and
2) as others in the thread pointed out, it is a very contrived and useless
test case for language comparison. Why does the Java and C code run
faster? Loop optimization. The java compiler and c compiler I used
optimized the loop away so the execution time is O(1). Perl did not
optimize the loop away. Could it have? I'm not sure if there are any
command line switches to do this type of optimization. Should that
be the basis to throw away the whole language? No. Pure execution
speed should be just one of your criteria and a very low one at that
(otherwise we'd all be programming in machine language).

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).
