Bad performance on alpha? (make buildworld)

Hi,
I run several buildworld's on both, an Alpha EV56 and a Intel PII. I'm
wondering that the Pentium beats the Alpha. Both systems have INVARIANTS*
and WITNESS* disabled. Furthermore, no special tweakups - nearly "out of
the box" configured.
Alpha EV45, 600MHz, single CPU

make -j4 buildworld 17171.15 real 14583.99 user 2242.81 sys
And I don't think CURRENT is that "faster" than 5.2.1. Why does (my) alpha
performs so bad? Some ideas? Is that behaviour common for FreeBSD/alpha or
did I missed something in my consideration?
