I don't quite follow the "send io to server unlimited" part. Doesn't that get limited by available number of requests? ie. if the server throttles, the in-flight requests will take longer to complete which exhausts the available requests and thus slows down the client. That's how it's supposed to work on the local machine too. Thanks. -- tejun
