dns,
1. actually i'm in this field around 15 years and know about OP since Igor was cracked cabarc - i.e. 9-10 years ago. moreover, i've heard about SS parsing about 15 years ago from author of BSARC. and you may find full overview of lz77 parsing methods i've put here at once.
2. my problem is that i know much more about compression that i have time to implement. initially tornado was targeted for fast, thor-like compression modes in freearc and here it does very well (1st place in MFC efficiency rating). now i'm experimenting with high-compression modes. by implementing overlapped io/OP/multithreading you covered these topics, so i've to experiment in other directions
3. now about lzturbo. tor 0.1 had switches:
Code:
-# -- select predefined compression profile (1..9)
-c# -- coder (1-bytes,2-bits,4-arith), default 4
while lzturbo 0.0.1 had
Code:
m:compression method (1,2,4) 1:byte-output fastest compression and decompression
2:bit-output
3:not implemented
4:best compression
l:compression level (1..9)
moreover, their speed/compression was close. moreover, you've quickly omitted "byte/bit" descriptions from your program and declined from describing your program (except its original points - io/OP/MT). you just don't know how MF/modeling in your program works
so, i have enough facts to be sure that lzturbo was build on tornado basis
that's even more exciting is that tornado 0.2 was available since June as part of fa sources, but you doesn't realize it. a few days after tor 0.3 release, new lzturbo version arrived, with -3* used my huffman encoder and -*1..-*8 used my lazy match finder. you have not used parts that doesn't increase ENWIK9 compression, though 
so, at this moment lzurbo is partial tor 0.3 clone plus new ideas you've widely advertized. i'm pretty sure that it doesn't contain anything written by you except multithreading/io/OP. you are probably from eastern countries and doesn't realize that you just break laws by stealing my code
technically, i'm not against lzturbo, of course - it implements improvements to tornado i have described at this forum
