Some time ago I've made myself a framework for such tests and have run it
against a commented loop. This test was run on a dual PIII/1000 Dell server.

    $hpr = _fwx_profile_start('Loop with end-of-line comment', true);
    for ($i = 0; $i < 1000000; ++$i) {
        $a += 1;        // this is an end-of-line comment
    }
    _fwx_profile_end($hpr, $i);
Average time per loop: 0.059 msec

    $hpr = _fwx_profile_start('Loop with inline comment', true);
    for ($i = 0; $i < 1000000; ++$i) {
        /* this is an inline comment */ $a += 1;
    }
    _fwx_profile_end($hpr, $i);
Average time per loop: 0.059 msec

    $hpr = _fwx_profile_start('Loop without comment', true);
    for ($i = 0; $i < 1000000; ++$i) {
        $a += 1;
    }
    _fwx_profile_end($hpr, $i);
Average time per loop: 0.059 msec

Conclusio: I didn't find any measurable difference in these loops, be it an
end-of-line comment, an inline comment, or no comment.
