<font size="2">Earl, </font><font size="2">that sounds interesting - but are you sure Pressflow does that currently; all I've located so far is this ancient</font><font size="2"> module </font><font size="2">(by David Strauss) <a href="http://drupal.org/project/pressflow_preempt">http://drupal.org/project/pressflow_preempt</a></font><font size="2"> that mentions such functionality ("</font>Based on the performance data Preempt collects, it may choose to rebuild cached items during cron operations.<font size="2">"). <br>
I'm looking further, of course, but if you have an URL for more info on that I'd much appreciate it.<br><br></font><br style="color: rgb(102, 102, 102);"><br>

</div></div>This is the Pressflow caching model. When David Strauss first got into<br>
Drupal, he did a lot of work with this kind of thing, where caching<br>
wasn't done when requested, but on cron.<br>
