The compile load is not a real compile load; it is an extreme exaggeration of what happens during a compile and this is done to increase the sensitivity of this test. It is _not_ worth trying to get a perfect score in this. > I'd like to see some results with X reniced to -10. Despite what the > 2.6 release notes say, this still seems to make a difference. Well of course it helps X - but then any X load totally fscks up audio on mainline and staircase which is why it's recommended not to renice it. Cheers, Con
