This wasn't a benchmark, or even meant as a test, but it was an interesting number nonetheless.
I installed bison today. As I have 3 different families of sytems (Sparc Solaris 8; Sparc Solaris 10; x86 Solaris 10) I have 3 copies of /usr/local, so build on 3 different systems. Anyway, after building bison (and the T2000 allows a very parallel make that some builds can take advantage of) I ran a make check.
The results were quite interesting. My sub $1000 Opteron 146 system took 107s. An old V880 (750MHz US-III) took 529s. The T2000 took a whopping 794s. This really isn't looking good.
