Re: Benchmark for Ruby

Once you know where Ruby is spending its time, play with compiler flags.
gcc has oodles of possible optimizations, and gcc itself was tuned by
processes like this. It's worth spending a lot of time compiling the
Ruby interpreter, since it's going to be run often.

Playing with compiler flags is of limited utility across the board.
The compiler flags for each platform *will* *differ*, and GCC
optimizations are different than native compiler optimizations (and
GCC isn't well-optimized off PPC and Intel; I will never compile
something with a non-native compiler if I can avoid it for any
reason).

I'm not interested in things that require compiler flag tweaks --
that's far too variant and should be done on a per-system basis. I'm
looking for a benchmark suite that show areas where the implementation
can be improved. I'm not looking for artificially limited benchmarks
where a simple tweak of an operating system option (e.g., ulimit)
enables the benchmark to run or run faster.

There's the difference.
