<h1>PHP Weather Speed Test</h1>
<p>If you've configured PHP Weather to use a database, then you might
be interested in knowing how long it takes to access the data in the
database. This is what this page is for, it will meassure the time it
takes for PHP Weather to retrieve and display a large number of
METARs.</p>
<p>If you have several different databases available to you, then you
can compare them using this page.</p>
<?php
if (empty($HTTP_GET_VARS['batches'])) {
$batches = 1;
} else {
$batches = $HTTP_GET_VARS['batches'];
}
$count = $batches*32;
?>
<p>We will now time PHP Weather while it retrieves and parses <?php
echo $count ?> different METARs. This will take a long time at first
because PHP Weather has to retrieve the METARs from the Internet, but
the second time you use this page it should go much faster because the
METARs can be retrieved from the database - that is, if you've configured PHP
Weather to use a database.</p>
<p>Select the number of METARs to use:
<a href="<?php echo $PHP_SELF ?>?batches=1">32</a>,
<a href="<?php echo $PHP_SELF ?>?batches=2">64</a>,
<a href="<?php echo $PHP_SELF ?>?batches=4">128</a>, or
<a href="<?php echo $PHP_SELF ?>?batches=8">256</a>.</p>
