Hi all!

Let me introduce my new LZ-based file compressor called BALZ. The main
benefit of this compressor is very good balance between:
+ compression ratio
+ compression/decompression speed
+ memory usage

It has 64 MB dictionary, and at compression it uses only ~130 MB
(about 2N!).

This compressor represents a glory of LZ-compressors. Forget about
Deflate - get really strong compression at the same speed...

Your web page only shows output file sizes. Can you also include some
execution time comparisons for both compression and decompression?

Do you plan to make the source code available?

How does it compare to 7Z?

Today evening I will add some timings. Maybe I primarily will compare
it with other command line compressors/archivers - e.g. RAR instead of
WinRAR, LZMA instead of 7-Zip... :)

As with my other projects like LZPX/QUAD I'm planning to release it at
SourceForge.net, but only after I finish working on it - i.e. after I
made all improvements available.

Currently, BALZ can easily replace LZMA with fast modes, being both
faster and stronger at compression. At some files LZMA with any
options can never beat BALZ, for example on FP.LOG. However, LZMA with
max/extreme modes overall is stronger than BALZ, as expected LZMA in
this case uses far much more memory and longer compression time.

Hello,

are there also some benchmarks on some standard file set ? Maybe we
could have a more precise idea of the compression performances seeing
the results for various file types.

Best and kind regards,
Stefano

I'll start using your app if you rename it to "Ballz McCracken." 'That
your real name by any chance?

BALZ might be short for Below Average LZ. If seriously, BALZ is a
parody on ROLZ (Reduced Offset LZ). At the same time it's a funny word
- "my BALZ compressor"... ;) You know...
