Has anyone looked at _why_ they are so slow? Do you have timing
information for a particular kernel flavor?
If I'm remembering correctly, local kernel builds on my G5 were quite
faster than what is in koji. Finding out why might be a good start.
Ok, so I did a cvs checkout of the devel kernel last night and timed a
simple 'make ppc'. That built both the UP and SMP ppc kernels, with all
the associated -devel and -debuginfo packages.
This was done on a dual-cpu G5 with 1.5 GiB of DRAM running F9. Gnome,
Evolution, X-Chat, and Rhythmbox were running, but it was otherwise
unused.
The results:
real 117m16.886s
user 133m27.480s
sys 20m47.314s
How does that compare with koji builds?
