Slight correction - CMUCL is only 1 order of magnitude slower.

Also, I just tried running the ackermann and harmonic tests from the
shootout and they run at the same (fast) speed on my machine as on the
shootout's machine. So it seems the problem is specific to raytracing-like
code.

I'm completely stumped.
