Did fastload speed up the protocol, or did it compress the data? I remember using other software for speeding up reading and writing from cassettes, but if I remember correctly this was achieved using compression.

It gets rid of the clock bit, synchronizing the two CPUs so that the 1541 can transmit 2 bits at a time.

It was still slower due to GCR decoding. Over the last 10 years people have started to write streaming GCR decoders too.
