Conclusion

Overall, I’m pleased with the performance of the Sun Ultra 20 M2. While this model (with an Opteron 1210) isn’t quite as fast as a low-end Mac Pro, it’s less than half the price of a low-end Mac Pro. Models equipped with faster Opterons (like the Opteron 1218) will certainly be more competitive when it comes to performance.

Another thing worth mentioning is that Solaris (and the Sun Studio compiler) outperformed Windows (and Visual C ) by almost 15%. Solaris outperformed Windows in almost every benchmark category, even outperforming Windows dramatically in some specific tests (such as some of the floating point benchmarks). If you’re working with processor-intensive tasks, Solaris might be the operating system for you.
