CLS - Fast LZMA2

[78372]

-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.

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)

[FitGirl]

Because Oodle Mermaid is better than fast LZMA2

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

Small test

SREP+4x4:lzma

Compressed 1 file, 1,444,079,652 => 666,703,063 bytes. Ratio 46.17%
Compression time: cpu 622.41 sec/real 206.39 sec = 302%. Speed 7.00 mB/s
All OK

SREP+FL2

Compressed 1 file, 1,444,079,652 => 679,032,090 bytes. Ratio 47.02%
Compression time: cpu 299.06 sec/real 103.33 sec = 289%. Speed 13.98 mB/s
All OK

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

[github]

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

Tested 5 files, 6,139,044,914 => 7,799,289,310 bytes. Ratio 78.71%
Testing time: cpu 212.50 sec/real 222.03 sec = 96%. Speed 35.13 mB/s

xt20+srep+fl2

Tested 5 files, 5,912,090,557 => 7,799,289,310 bytes. Ratio 75.80%
Testing time: cpu 343.20 sec/real 478.89 sec = 72%. Speed 16.29 mB/s
All OK

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