I've got a script that tars an entire source code directory (around 800MB), and I want it to run as fast as possible. GNU Tar, for some reason, was kind of slow when untarring. I was wondering if anyone's already made this comparison and knows which application has the fastest tar/untar implementation. For Windows, btw.

A:
http://www.7-zip.org/ may be a bit faster, haven't tested them directly against each other. One consideration may be to just get your tar script to store the files in a tar archive instead of compressing them, but that is only if filesize is not a consideration. If you dont need them to get any smaller, just to be stored in a single tar file, then turning the compression off altogether will give you a significant benefit.
Also, just check and make sure that you dont have an on-access virus scanner running in the background, as that will rescan your tar file every time it changes and significantly add to your tarring time.
the contents of a tar are never compressed, tar doesn't support compression. Instead the entire tar file is commonly compressed with gzip.

Comparing GNU tar with what?
The performance of your tar program will ultimately (when you've removed factors such as anti-virus) be I/O-bound, so your best hope to get a faster tar is to get faster hardware.

I tested 7zip against GNU tar, and it's slower.. :( WinRAR is also slower.
