Actually, even on very fast connections, the time to download dwarfs the time to decompress, untar, or print the names. The best way is tail -f -n+0 linux-n.n.n.tar.bz2|bzcat -vv|tar -xv.

    This is truth. But most people would be amazed at the actual time verbose output can cost your program. Printing is very expensive, I remember when coding a big branch-and-bound project for the cap-mst problem in college, it was responsible for like 70-80% of the total running time, which was huge. And I just couldn't believe it. So I think most people (specially non-programmers) have no idea how expensive it can be, and I can tell you I rarely use -v, unless I need it.

    Since I run my own proxy at home, I can assume that most downloads live in the cache, so I just do: 
    curl <URL> | tar -jx
or
wget -O - <URL> | tar -jx

    most of the time.
