Benchmarks When running tests, installing operating systems, and compiling software for my Ultra 5, I came to the stunning realization that hey, this system is 64-bit, and all of the operating systems I installed on this Ultra 5 (can) run in 64-bit mode.

Additional 32/64 bit benchmarks
by nitrile on Thu 22nd Jan 2004 22:16 UTC

A synthetic test suite I've used for benchmarking unix systems is nbench ( http://www.tux.org/~mayer/linux/bmark.html ). It's available as source and has a small variety of different individual tests which, though are each detailed individually aren't reproduced here.

Ultra-10, USIIi 333MHz/2MB:

--------
gcc -s -static -Wall -O2 -mpcu=v9 -m32
nbench: ELF 32-bit MSB executable, SPARC32PLUS, V8+ Required, version 1 (SYSV), statically linked, stripped

==============================LINUX DATA BELOW===============================
CPU :
L2 Cache :
OS : Linux 2.4.21
C compiler : gcc-3.2
libc : ld-2.3.2.so
MEMORY INDEX : 1.076
INTEGER INDEX : 1.257
FLOATING-POINT INDEX: 1.760

--------
gcc -s -static -Wall -O2 -mpcu=v9 -m64
nbench: ELF 64-bit MSB executable, SPARC V9, version 1 (SYSV), statically linked, stripped

==============================LINUX DATA BELOW===============================

Running tests multiple times produces some variation, but in general they are all fairly close.
