quickest most efficient way to generate a page hit
<p>I am trying to crawl every page on my site (ran by a cron) to update data. There are roughly 500 pages.</p>

<p>I have tried 2 options.</p>

<ul>
<li>PHP Simple HTML DOM Parser</li>
<li>PHP get_headers</li>
</ul>

<p>Using either of the above, each page roughly takes 1.402 seconds to load. In total this takes about 570 seconds.</p>

<p>Is there a more efficient way of doing this?</p>
