Thank you very much for your suggestion, which might have been valid. As you
did mention, it wasn't until linux 2.1.27 that the SMP flag was set as a
default, and I had noted in my previos mail that even since 2.1.26 I thought
that there was a slowdown.

I also copy this message to the list, so others may see that it is not an
erroneus setting of the SMP flag that caused this. I don't thereby excluse
other erroneus behaviour, but haven't yet seen anything that would suggest

This is a good opportunity to say:

Always check the top Makefile (makefile) before you start building!
