But different programs. As said by others, most difference comes from
the application itself. Let's compare default bzip2 and one compiled for
p4:

# time bzip2 -9 < out.wav > /dev/null 

real    0m48.989s
user    0m41.930s
sys     0m0.220s
# time /tmp/bzip2-1.0.2/bzip2 -9 < out.wav > /dev/null 

real    0m39.017s
user    0m38.920s
sys     0m0.090s

Do you see now that 8 of your 10 percent come directly from the
application code and other two maybe from the optimized libc? There is
not{hing| much} we have won using an optimised kernel. But the placebo
effect has been demonstraded once again.

MfG,
Eduard.
