I have an old, slow machine here which I am going to use to perform
some real world testing, and I'll post the results when I'm done. But I
suspect that building a kernel on this machine, even a small one with
just the drivers it needs, will take much longer than unpacking the
sources. So anyone worrying about performance would rather rely on
cross-compilation, and in turn can afford whatever decompression tool
is needed.
On zaurus, kernel compilation takes 4 hours. (I.e. "one night"). So
that one is ... well ... done overnight.
Untar is something I normally wait for, since you need to run
(interactive) oldconfig after that.
If the download takes m minutes and unpacking and unarchiving tar.gz
takes another n minutes, what difference does it make for this workflow
when instead m + p minutes are spent for download + unpacking and
unarchiving tar.bz2 or tar.xz?
