Yes, and rsync does it. That's why it runs two processes (generator and receiver) in the destination. -- Please use reply-all for most replies to avoid omitting the mailing list.

Oh, and if it buffers requests sent to its STDIN, that's fine. To actually complete requests in parallel, you'd need a multithread or multiprocess app, and that's complicated. The proper term for what I'm suggesting is probably "pipelining". -- Travis is an organic computer peripheral.

Just curious if the protocol sends a request and waits for a response, or whether it can multiplex multiple requests on a single connection. This could improve performance over high latency links, if a lot of time is spent waiting for the response (i.e. when the hashes match). -- Travis is an organic computer peripheral.
