I made a test for several DLL

http://gvollant.free.fr/zlib125_dll_collection.zip

 

 

this include the three latest DLL from Cosmin

and my build with Visual Studio 2010, with and without assembly code, with
and without using profile guided optimisation

 

usage for test

go do testzl directory

start

dotst <filename_to_test_compress> 32768 32768

or with maximal compression

dotst <filename_to_test_compress> 32768 32768 9
