Zip compression level different from v2007 to v2009



  • Hi there, I imagine there’s a resonable explanation I’ve missed in some release note or something… but I’ve found this a little odd:

    40 folders, 187 files, total of 1.41 MB

    v2007 (v10.02):
    Maximum ZIP = 924 kb

    v2009 (v11.03):
    Maximum ZIP = 961 kb

    What am I missing…?



  • Sorry v2007 is 10.22 and NOT 10.02…

    try 2010 🙂



  • Why… won’t v2010 just compress it at 998 kb - LOL ?

    But seriously, can anyone say if there was perhaps a ‘change’ in 2009 from 2007 that might otherwise be intended to result in “better” compression in other cases / byte patterns etc that just happens to NOT work out so well in THIS case?

    we changed/updated engines between all these versions… PA 2010 has our latest engine, so if you want to make any comparos thats where to look.
