IPP and zlib

1. In IPP Samples 7.1 you have the zlib source adapted for IPP. I took that source and compiled it instead of the usual native v1.2.7 source. It reduced decompression time 20% to 50%. Is that what is expcetd? To me it was a little disapointing.

2. Your code is based on version 1.2.5. It is pretty old by now. When will it be updated?

3. In gzread and gzwrite and I had to

#if defined(WIN32)
#include <windows.h>
#include <tchar.h>
#endif

You use DWORD with declaring anywhere for instance.

Hello, 

Thanks for the feedback,  Some more performance data we had test here:

The performance you tested looks fine.  I am also tracking the request on new v1.2.7 support. 

Regards,
Chao
