ZLib Stream Checker

[Razor12911]

This program determines whether you can use a zlib precompressor like precomp on certain input or not and gives estimates about the inflated data size, how many streams found etc.

Estimated scanning speeds:

Input: (Mathematica_9_Setup.exe) (1,210,695,064 bytes)
Normal: 33780.55 kb/s (no streams found)
Brute: 1651.28 kb/s (no streams found)


Input: (linuxmint-17.3-xfce-64bit.iso) (1,555,709,952 bytes)
Normal: 24504 kb/s (34543 streams found)
Brute: 16513.57 kb/s (34793 streams found)

Changelog:

Version 2.2 (Current)
-Improved normal scanning speed by 13%
-Improved brute scanning speed by 8%


Version 2.1
-Improved brute scanning speed by 9 times
-Fixed regional settings bug


Version 2.0
-Added brute scanning
-Added select directory as input instead of single file.


Version 1.0 (Initial)

Here are the test results Sir...With Fast mode, it locked a max. speed of 664.3 MBPS with max. Threads 27 during compression (Out of which max. were of Interface)... There is one interesting thing though, it was able to read all the processed streams inside the data output of Reflate & then inflate them back, in 1254.test.

1254.test:
Found streams: 10309

book1_best_deflate.zip:

But for the brute mode, it didn't find any streams in that test file...Although Brute was able to Decompress .zip compressed with Deflate, with a max. speed of 47.2 MBPS and a max. thread of 24.
