I think it should make you feel better to know that there is something very
wrong here. This is more than a factor of 10 slower than a 100 step dhfr
calc should be on a 667MHz ES40 in 4-way smp. From what you sent, I don't
see what the problem is, though.

Is it possible that something else was running on the machine when you made
this measurement?
