Decompression speed improved in 64-bit mode
Decoding functions are now also immune to out-of-buffer read errors (note : they were already protected against malicious out-of-buffer write attacks)

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.
