OTOH if the goal is to measure "operating system" performance, this must also include the compiler, libraries and all. (for example, what does Solaris default to nowadays? I think it ships with gcc but not as default). The hold on gcc 4.3 in FreeBSD is, after all, political (licencing). If FreeBSD base ever switches to LLVM+clang, this means libc will be compiled with a non-gcc compiler which will forever change the performance for simple "real world" benchmarks.
