gzip verses 7zip, 7zip wins

Just had to compress a large file again. I asked was gzipping better than 7zip? So I did both.

• The base file directory took up 34.37 GB. 
• I am running Mac OS X 10.6.8. 
• I installed p7zip (brew install p7zip).
• Two commands:
• 7z a largefile.7z large_file_directory
• tar czvf largfile.tar.gz large_file_directory
• Resulting sizes:
• 7zip = 22.43 GB
• gzip = 25.07 GB
