So, have we by now established that a one-liner which does absolutely nothing in the loop, as I suggested, does not run in a time comparable to the one that uses the no-op inline function, but runs considerably faster?

I don't think we have, as it was never really the issue.
The issue was more about some apparent additional overhead in calling XS subs on Windows, and what to do about it.

I do, however, think it is very likely that code that does nothing 10 million times will execute significantly faster than code that calls a no-op 10 million times - and that your suggestion is most likely quite correct.

Cheers,
Rob

• 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).
