7zip is the program.  It unzips many formats, with the standard 
zip format being one of them.  The parallel d program is three 
times faster at decoding the zip format than 7zip decodes the 
same file on the same ssd drive.  That is an appropriate 
comparison since 7zip has been my utility of choice for unzipping 
zip format files on windows for many years.

I provided the source code in the examples folder for the 
complete command line utility that I used, so you may build it 
and compare it to whatever you like and report the results.
