Okay, thanks, I'll take a look at that. There are also some open source
conformance test-suites, I believe.

Good catch; no, obiviously you can't run the benchmark on a machine being
used for something else at the time and expect to get reasonable results.
However, since you'll have to run the benchmark on different architectures
anyway, you might as well run them on separate machines that are idle
overnight or the like.
Also, it does give you a rough idea on conformance if the benchmarks break
too badly :) I was thinking more in the terms of "breaking some
optimization". The problem with optimizations is that they're quite
platform specific and sometimes longer to run than simple conformance/
regression tests, so they're difficult for a single developer to run. In
addition Kaffe has pretty good conformance, but it would appear
performance could use some work.
