When I upload files using chunk jquery file upload plugin (https://github.com/kaltura/chunked-file-upload-jquery ) I have upload speed much less than regular upload via PHP :
( $config = new KalturaConfiguration($partnerId);
$config->serviceUrl = ‘http://www.kaltura.com/’;
$client = new KalturaClient($config);
$movie = $_FILES[‘file’][‘tmp_name’];
$token = $client->media->upload($movie); )
When performing a chunked upload operation, you have the overhead of splitting the original file into chunks at the client side and then also reassembling the file once all the chunks arrived on the server side. That overhead is of course in relation to how big the complete file is but it can certainly make a difference if the file is very large.
