Lord.Freddy: Nothing. I haven't met him yet, the Blizzard compressor. Testing now in next hours/days.

DLZ = (D)ds modeled (LZ)ma v0.2.2 by profrager

Quick tests: 2* Faster than LZMA and comparable ratio.

Code:

Tested 164 files, 13,760,715 => 83,606,836 bytes. Ratio 16.46%
Testing time: cpu 0.16 sec/real 29.28 sec = 1%. Speed 2.86 mB/s

Tested again, packed all files in one ARC file, in store mode and packing in Blizzard. Small, default blocksize its better!?

Code:

bliz.exe c bmp_store.arc bmp_.blz 300000000  ---> 13 762 777 byte
bliz.exe f bmp_store.arc bmp_.blz 300000000  ---> 13 963 348 byte
bliz.exe f bmp_store.arc bmp_.blz  ---> 13 604 705 byte
bliz.exe c bmp_store.arc bmp_.blz ---> 13 396 429byte

Quick note: Best results get in use 8MB blocksize (smaller/bigger, worse results): 13 369 598 byte
