OOZ Review

[panker1992]

Ok since several people asked me to put OOZ into Masks I finally decided to shed some light to it.

oodle is an API created to pack Game files which are meant to be unpacked at
Ram Speed.

It's a bad idea to use it for repacks and here is why:


Leviathan:
================================================== =====
ooz -1 --leviathan = 37.15mb/sec Output_Ratio = 24.20%
ooz -2 --leviathan = 31.68mb/sec Output_Ratio = 23.95%
ooz -3 --leviathan = 12.95mb/sec Output_Ratio = 23.06%
ooz -4 --leviathan = 12.99mb/sec Output_Ratio = 22.76%
ooz -5 --leviathan = 1.23mb/sec Output_Ratio = 21.09%
ooz -6 --leviathan = 0.88mb/sec Output_Ratio = 20.86%
ooz -7 --leviathan = 1.01mb/sec Output_Ratio = 20.68%

Kraken:
================================================== =====
ooz -1 --kraken = 64.55mb/sec Output_Ratio = 25.67%
ooz -2 --kraken = 53.29mb/sec Output_Ratio = 25.28%
ooz -3 --kraken = 36.67mb/sec Output_Ratio = 24.38%
ooz -4 --kraken = 29.47mb/sec Output_Ratio = 24.03%
ooz -5 --kraken = 2.25mb/sec Output_Ratio = 22.23%
ooz -6 --kraken = 1.35mb/sec Output_Ratio = 21.98%

Hydra:
================================================== =====
ooz -1 --Hydra = 24.05mb/sec Output_Ratio = 24.52%
ooz -2 --Hydra = 23.34mb/sec Output_Ratio = 24.30%
ooz -3 --Hydra = 16.00mb/sec Output_Ratio = 23.43%
ooz -4 --Hydra = 9.98mb/sec Output_Ratio = 23.15%
ooz -5 --Hydra = 1.38mb/sec Output_Ratio = 21.52%
ooz -6 --Hydra = 0.89mb/sec Output_Ratio = 21.20%



Other LZ Compressors:
================================================== =====
lzma2/xz d256m:mt1 = 5.49mb/sec Output_Ratio = 20.67%
lolz -d256m -mt1 = 0.72mb/sec Output_Ratio = 18.62%
Zstd --long=31 --ultra -22 -T1 = 4.88mb/sec Output_Ratio = 23.39%
Lizard -49 -BD = 4.77mb/sec Output_Ratio = 27.60%
lz4 v1.8.3 -12 -DB -B7 = 18.18mb/sec Output_Ratio = 31.91%
Lzturbo -49 -b64m -p1 = 2.5mb/sec Output_Ratio = 21.37%

Other Reference Compressors:
================================================== =====
cls-rzo (mt=8) chunk size = 128m Dictionary Size = 64mb = 4.85mb/sec Output_Ratio = 20.64% (Reference)
7Zip Shelwien Max settings N/A Output_Ratio = 20.71% (Reference)

PS: these are for Reference, comparison is irrelevant but they are here nonetheless!!

Not only it under-performed to even lzma but the packing speed is delusional to the point i didn't bare to make the 7 8 9 max out settings.

However unpacking speeds are anywhere from 600MB/sec to 1.100MB/sec which is cool but packing with xtool+srep alongside it will bottleneck it to somewhere 150 ~ 200mb/sec. (See Below)

Ram usage is around 1GB at -1 up to 4.5GB to -5, -6 which makes it hard to implement a CLS, and ratio is so bad that chunking it will further break it.
