I meant to say that the compiles of the trivial benchmarks took almost the
same user CPU, the benchmarks themselves are CPU bound and do no I/O.
The system CPU on the Celerity was twice a Pyramid 90x (i.e.  6.5 vs 2.9)
which I suspect was stack register copy times.

The elapsed real times were more like 2+ than 3 times.  (I just found my notes).
