-m1=lzma2
Here change lzma2 to your favourite compressor.
and -txz to-t7z.
Note that it won't support stdio

Nice one. But I didn't understand at all. What different fast lzma2 and the 7z [lzma2]? Can you explain how they can compress between the size of huge files? Just ask. :D

Also I like how you create with those codes from GitHub to cls. I can understand the code was almost same like delphi. :)

Fast lzma2 uses a different matchfinder and faster than normal lzma2. It can use multiple threads more effeciently.

i got a very negative ratio using it with oorecm (oodle mermaid)

Because Oodle Mermaid is better than fast LZMA2

Thanks. This gives nice good compression ratio at super fast speed

Small test

SREP+4x4:lzma

SREP+FL2

I Use Reflate+Srep+Delta+nz as kompression. The Speed is slow in both Ways. I will test the FL2

the fl2.zip (569.0 KB ) found in #10 seems to produce almost the same size (0.01% smaller) result but is 3% slower than fl2_fpc.zip (137.7 KB )

Unpack test

xt20+srep+4x4:lzma

xt20+srep+fl2

does this fl2 (cls dll/exe) support pass in compressing levels or any other parameters?
