Greatly improved compression and decompression speed, at the expense of some compression ratio.
Most of the change is due to a modification in the performance parameter (HASH_LOG) now set to 12, to match Intel L1 cache processors.
You can change it back to 17 to get back previous compression ratio.
AMD users are invited to try HASH_LOG = 13, since AMD L1 cache is twice larger.
