Ok, repeated the tests with make -j3 'MAKE=make -j3' bzImage
I ran xosview to monitor the load.
The load values for 2.2.18 seemed to stay higher longer than
for 2.4.0-test12. I recorded the peak load observed.
For comparison, with make -j3 bzImage, the peak load was much
lower, about 2.7.
Task: make -j3 'MAKE=make -j3' bzImage for 2.4.0-test12-pre7 kernel tree.
Numbers are seconds to build.
New results:
1 2 3 ave.
