I have a PHP script that used to run on regular curl requests and
decided to switch to curl_multi for the speed benefits. With the script
only running for a few hours at the end of the day, my cpu time reports
from averaging around 45 minutes to 6 hours yesterday.

This is the only thing I changed in the last 24 hours, so I know the
curl_multi is the culprit. I can also see sharp jumps in processor time
right after I switched to curl_multi

Here's the code: (my script pulls from 5 sites)

$urlArray[0] = "http://website.com/";
$urlArray[1] = "http://anotherwebsite.com/";
$urlArray[2] = "http://andanother.com/";
$urlArray[3] = "http://onemore.com/";
$urlArray[4] = "http://lastone.com/";

$mh = curl_multi_init();

foreach ($urlArray as $i => $url) {
       $conn[$i]=curl_init($url);
       curl_setopt($conn[$i],CURLOPT_RETURNTRANSFER,1);
       curl_multi_add_handle ($mh,$conn[$i]);
}

do { $n=curl_multi_exec($mh,$active); } while ($active);

foreach ($urlArray as $i => $url) {
       $res[$i]=curl_multi_getcontent($conn[$i]);
       curl_close($conn[$i]);
}

Perhaps there's something wrong with my code? It seems to be in order.

What's the problem?

Thanks,
-Brian
