Ah wait, so you have 8 groups of cycle soakers vs 1 group of desktop? That means your desktop will get 1/9 th of the total time and that is almost so: 2.69+24.59+12.84+10.45+3.44+.39 = 54.4 vs (64.32+64.92+63.12+61.46+63.38+61.45+63.44+64.92)/8 = 63.37625 Which isn't too far off. This really appears to be a case where you get what you ask for. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
