the real bottleneck is not the rpmbuild itself (with ccache it cab be

most of the time is in yum, python tar, gzip etc which all use only one
cpu/core and it's very slow!
This is very bad performance, on my 2.5GHZ Athlon dual core with 4 GB
RAM a very simple src.rpm (pyhunspell-0.1-2.fc12.src.rpm) rebuilds in 18
seconds with tmpfs plugin enabled.
Another bottleneck could be the connection to your Fedora mirror.
