JiffyDOS specifically speeds up the transfer of data bytes on the Commodore serial bus. For compatibility reasons commands are sent using the stock Commodore protocol, but all actual data transfers (both in and out of the computer) are sped up unless the peripheral in question does not speak the JiffyDOS protocol.

As far as I know it’s only got “load” in the name because that’s the most common use case. I was under the impression that it is a (perhaps minimally) complete implementation and can both read and write data at JD speeds. Does its home page actually, explicitly claim otherwise?
