Does anyone know what the best (or a really good) way is to load external files (about 10-20) from an api with performance in mind. Each session has different content. Currently I try "file_get_contents" but experience serious performance issues. I'm not really familiar with Curl but it seems performance wise to beat the good old PHP way. Any ideas/examples?

You could also use curl multi to grab multiple files at once, there is a tutorial here:
http://www.phpied.com/simultaneuos-http-requests-in-php-with-curl/
<?php //Copy & pasted from the above link function multiRequest($data, $options = array()) { // array of curl handles $curly = array(); // data to be returned $result = array(); // multi handle $mh = curl_multi_init(); // loop through $data and create curl handles // then add them to the multi-handle foreach ($data as $id => $d) { $curly[$id] = curl_init(); $url = (is_array($d) && !empty($d['url'])) ? $d['url'] : $d; curl_setopt($curly[$id], CURLOPT_URL, $url); curl_setopt($curly[$id], CURLOPT_HEADER, 0); curl_setopt($curly[$id], CURLOPT_RETURNTRANSFER, 1); // post? if (is_array($d)) { if (!empty($d['post'])) { curl_setopt($curly[$id], CURLOPT_POST, 1); curl_setopt($curly[$id], CURLOPT_POSTFIELDS, $d['post']); } } // extra options? if (!empty($options)) { curl_setopt_array($curly[$id], $options); } curl_multi_add_handle($mh, $curly[$id]); } // execute the handles $running = null; do { curl_multi_exec($mh, $running); } while($running > 0); // get content and remove handles foreach($curly as $id => $c) { $result[$id] = curl_multi_getcontent($c); curl_multi_remove_handle($mh, $c); } // all done curl_multi_close($mh); return $result; } ?> <?php $data = array( 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Pearl+Jam&output=json', 'http://search.yahooapis.com/ImageSearchService/V1/imageSearch?appid=YahooDemo&query=Pearl+Jam&output=json', 'http://search.yahooapis.com/AudioSearchService/V1/artistSearch?appid=YahooDemo&artist=Pearl+Jam&output=json' ); $r = multiRequest($data); echo '<pre>'; print_r($r); /* Array ( [0] => {"ResultSet":{"totalResultsAvailable":"633","totalResultsReturned":... [1] => {"ResultSet":{"totalResultsAvailable":"105342","totalResultsReturned":... [2] => {"ResultSet":{"totalResultsAvailable":10,"totalResultsReturned":... ) */ ?>
Or curl php docs http://www.php.net/manual/en/function.curl-multi-init.php
