File upload and php... not a beginner question...

Hi, everyone know how to upload files from the browser to your web server using multipart-form method with move_downloaded_file() php function. But... It's a slow method for multiple files & huge files transfert. I'm currently working on a big photo album tool, and I want to provide user the ability to upload a lot of jpeg files in one time... The big problem with form is it's too slow... Does anyone know how to by-pass this ( with java or other tools )?????
