PAQ7 vs. ZIP

(PAQ8 was mentioned in the forums page to be included in KGB archiver 2.0, but the beta version has PAQ7)

Fact known in life, everybody uses zip a lot! Zip can be decoded by every OS quite easily and fast. Zip rules source archives and executables (although Rar archives have been seen there).

Fast forward 7 years into the super processors of tomorrow (quadcore K8L and Core 2 Duo Extreme) which can make 35% better compression ni amazingly high compression ratios that PAQ7 will give you. Zip still wins for any archive.

For a 35 MB file it will take a good 40 minutes on a Pentium 4 with 2 GB of RAM (and it's running in background on taskbar) and Zip will do this in under 50 seconds with 35% worst compression. So download and extraction of the zip file would take less no matter what broadband you have then the time saved by downloading a much smaller KGB file!

Now if you want to cram 35% more information on a CD using KGB is a good idea. I would do it. In fact I put all my files in 7zip now-a-days, but that is just me. Everybody who makes a open source program wants to put it in zip /w bzip2 compression container!

Point is doesn't anyone feel zip is dated and want to use PAQ7 in KGB Archiver 2.0 (comes out February 14)?
