You can make the call asynchronous using @Asynchronous

The server should be able to handle any (reasonable) number of simultaneous requests: just let the upload happen and do something else!

Now, to do that on the "same" page as the upload is not possible if you are using plain-old HTTP POST with a form. Instead, you'll have to use one of those Flash-based upload tools or maybe there is one in Javascipt you can use that will send the upload some other way (XMLHTTPRequest?). Then you can have the upload run but the page itself is still functional.
