Trust me when I tell you that a P4 w/ HT is *nowhere* near the speed of |
11 |
true SMP. You're better off going with your arbitrary calculations |
12 |
below. |

While I do think this information is useful, I still think the best |
15 |
method is to come up with a new number, rather than time. A good one |
16 |
(stolen from LFS) is the BU or Bash Unit. The time it takes to compile |
17 |
bash is always 1BU. |

SMP is ignored, since it skews the results. So would distcc... The idea |
20 |
is not to even try to give the exact time for emerging things for |
21 |
everybody, but rather to have a strong baseline "average" that hits most |
22 |
people. |
