kernel compiles aren't very expressive as long as you dont specify a
particular config. There is a huge difference between a so-so kernel and
say one which has all modules built...
Extracting a 2.6.10 tarball, running make menuconfig once, without
changing anything and just saving, and then "make -j4 bzImage" results in:
Kernel: arch/x86_64/boot/bzImage is ready
real 1m50.664s
user 3m7.761s
sys 0m28.861s
Yes, that is below 2 minutes real time on a 2CPU opteron.
