The new Petrel protocol uses a simple data compression scheme to reduce the transfer times. The data is broken up into blocks of 32 bytes each. Each block except the first is XOR'ed with the previous block, creating large runs of zeros due to the similarity of the data. The zeros are then run-length encoded (RLE) to save space.
