It take about 1 second locally -- but there is no reason for it to make the round trip. Calling my JS method using oncomplete means that the re-sort doesn't happen until after the roundtrip.
I'm doing a render :nothing on the server. With Mongrel in a production env this would probably be faster -- I just don't want to make the trip for No Reason.

I'm not sure why an asynchronous roundtrip to the server is not quick and light. Even if the server takes a while to respond, the user doesn't have to wait for that response, and in fact shouldn't even realize anything is still pending.
