One of my now-retired colleagues worked on real-time compression, and he told me that the Alpha AXP processor was very weak on bit-twiddling instructions. For the algorithm that was ultimately chosen, the smallest unit of encoding in the compressed stream was the nibble; anything smaller would slow things down by too much. This severely hampers your ability to get good compression ratios.
