Also check with gettimeofday to compare with wall clock time.

A:

I would try to correlate the time with the shell's time command, as a sanity check.
You should also consider that the compiler may be optimizing the loop. Since the memset does not depend on the loop variable the compiler will certainly be tempted to apply an optimization known as loop invariant code motion.
I would also caution that a 10MB possibly in-cache clear will really be 1.25 or 2.5 million CPU operations as memset certainly writes in 4-byte or 8-byte quantities. While I rather doubt that this could be done in less than a microsecond, as stores are a bit expensive and 100K adds some L1 cache pressure, you are talking about not much more than one operation per nanosecond, which is not that hard to sustain for a multi-GHz CPU. 
One imagines that 600 nS would round off to 1 clock tick, but I would worry about that as well.

 Q:

Keypress is not called anymore after form inside jquery ui modal box is hidden

I have a jquery UI modal box that contains a form.
I declared keypress event to handle Enter being pressed.
If I hide the form contained in the modal box, the keypress event is not called anymore.
This behaviour is reproduced here: https://jsfiddle.net/patrick29/jqp4wp77/
$('.dialog').on('keypress', function(e) {
    if (e.keyCode == $.ui.keyCode.ENTER) {
        submit();
    }
});
function submit() {
    alert('ok');
    $('.dialog form').hide();
}

First time Enter is pressed I receive ok message. Then form is hidden and second time Enter is pressed I do not receive ok message anymore.
Do you know why and how I can hide form and still have keypress event work?
Thanks!

A:

You can do something like this instead of.hide();
$('.dialog form').css({
  opacity: 0
});

 I would sample to correlate the meter with the shell's time command, as a sanity arrest.

  Q: 

 Keypress is not called anymore after form inside jquery ui modal box is hidden 

 I have a jquery UI modal box that contains a form. 
 I declared keypress event to manage Enter being pressed. 
 If I hide the mannequin contained in the modal box, the keypress event is not called anymore.

 inaugural time Enter is pressed I receive ok message. Then form is hidden and second fourth dimension Enter is pressed I do not receive ok message anymore. 
 Do you know why and how I can shroud form and however have keypress event work?
