Attached are timings from various runs with bzip2, gzip, and no
compression. Summary: gzip kicks butt. Mr Tibbitts was correct.
Attached is a diff to change the default to gzip. :)
Here is a summary (warm cache):
No caching: real 1m36.247s
build bz2 cache: real 4m28.174s
build gzip cache: real 2m25.889s
build nocomp cache: real 1m47.684s
use bz2 cache: real 1m13.208s
use gzip cache: real 0m20.854s
use nocomp cache: real 0m24.060s
The numbers above were from building a very small RPM which has no
compilation.
