Benchmarks "In January we published a review of the AMD Shanghai Opteron CPUs on Linux- when we looked at four of the Opteron 2384 models. The performance of these 45nm quad-core workstation/server processors were great when compared to the earlier AMD Barcelona processors on Ubuntu Linux, but how is their performance when running Sun's OpenSolaris operating system? Up for viewing today are dual AMD Shanghai benchmarks when running OpenSolaris 2008.11, Ubuntu 8.10, and a daily build of the forthcoming Ubuntu 9.04 release."

performance scalability

The phoronix test suite is still under development.

One crucial way to make it more useful is to include scalability tests.

OS-A is faster than OS-B on 1 cpu core for a test. But will OS-B maintain performance as number of cpu cores increases while OS-A degrades?

Solaris is known to be slow for many microbenchmarks. That's not why peopel buy it. Its scalable to large hardware and workloads. Better tests would reveal the nature of this scalability.

They should start contributing to OpenSolaris. How about Bluetooth!!! ;-)
