But I have belatedly realized that it's a really good idea to use make -j12 to build kernels and the world. With 4BSD and dnetc running, I can now buildworld in 3512 seconds (down from 20477), and with ULE in 14193 seconds (down from 50290). Peter's patch got it down to 13755 seconds. Also, I have to belatedly admit that my snarky March 23 message to Mark Millard (claiming that all you had to do to run dnetc was to type "service dnetc start") omitted the necessity of doing some first run configuration. I apologize. -- George
