I ran the Gabriel benchmarks included with OpenGenera (SYS:EXAMPLES;GABRIEL-BENCHMARKS.LISP). I'm running on a 533MHz Alpha 21164 with 512MB RAM. I've published the results. Ranier Joswig sent me his MacIvory3 results for comparison.
Comparing the results, OpenGenera on the Alpha system is 3 times faster on most benchmarks except for floating point. For floating point code, OpenGenera is up to 38 times faster (FFT benchmark) than MacIvory3. Given the Alpha's FPU, this is not at all surprising.

Somehow I would have expected better numbers and was under the impression that I have seen higher speedups. Hmm, did u really compile the benchmark? ;-)

Yes, I compiled the file: I initially loaded the file in the editor and then gave the command "Compile Buffer" before starting the benchmark.
David Schmidt has quoted a factor of 4 difference between a OpenGenera on Alpha 500MHz and an XL1200. I believe a XL1200 and a MacIvory Model 3 have similar performance.
I am going to try to benchmark on a 500MHz Alpha 21264.
