A Look at Solaris 10 and Sun's Dual Core Fire V40z

Compiling
We put a particular emphasis on compiling because it stresses the entire system (hard drive, processor and memory) but also because any *nix user knows, compiling is no fun on a slow machine.
GNU Make 3.79.1 / GCC 3.4.2
While GCC isn't multithreaded, we can run multiple jobs using the -j command in make. Below, you can see the significant improvement on performance going from 1 to 3 to 5 jobs. We used the commands as below to compile the Linux 2.6.4 kernel from kernel.org. The kernel is set for a cross-compilation of a default x86_64 machine:
# yes "" | make config
# time make -jX
There were minor advantages of the Solaris compilation over the SLES one. Like most of our other tests, as our compilation moved closer to nine jobs, the reduction in processing time was not quite linear. We do see considerable improvements in speed, but we really aren't getting all of the bang for our buck.
We also threw in some compile tests of entire GCC base, which take significantly longer than the Linux kernel to compile.
You'll notice pretty much the same problems from the Linux kernel compilation test; scaling becomes an issue as we increase the number of jobs. We see a 43% performance increase over the quad Opteron 250 V40z; certainly impressive but we would like to see more.

The Database benchmarks are likely bottlenecked on storage. Attach a high-speed array with multiple disks, and the scaling would be much more linear vs. 2-way.ceefka - Thursday, June 30, 2005 - link
It would be nice if other Opteron-builders would add to the test so we can get an idea of how well the Opteron is implemented.I'd say webspace is best served with dualcore Opterons. 90% gain! Holy moly!
#23 I have worked as a temporary at Sun in The Netherlands in 1987 when they were about to release their 4/ series. Their 3/ machines were already considered top notch then. They offered workstations with an optical mouse that moved over a special gridpad and full color screens. That was really something special then. No AMD CPUs at that time.
To be perfectly honest as well, I also didn't know them before I worked there ;-)

SuSE Linux Enterprise not enterprise enough for u?KristopherKubicki - Thursday, June 30, 2005 - link
hondaman: This is why we used SLES this time around instead of RH9. Unfortunately the previous single-core V40z tests were all done a few months ago when we had that machine.Kristopher

Wow, I wish my company had a use for a system like that. I'd take a paycut just to be able to play with it for a while... damned fine enginering on both Sun and AMD's part. And to be prefectly honest, I never really payed Sun that much attention until they started using AMD procs. Everyone else needs to get with the program and give AMD the market share they deserve...oh wait...I'll stop there.slashbinslashbash - Thursday, June 30, 2005 - link
#21: Read the comments and you'll find your answer.Kristopher: Page 7, "Apache Benchmarks" text:
"It's also interesting to note the difference between Solaris 10 and SLES 9 here. As the threads increased, there was a wider gap between performance of the Solaris configuration and the SLES configuration in favor of Solaris."
The graph on that page shows the opposite, with SLES outperforming Solaris.

wait why the xbox360/ps3 article taken down?hondaman - Thursday, June 30, 2005 - link
can you swap suse with a real enterprise os like rhel?themelon - Thursday, June 30, 2005 - link
I guess I should have kept reading.Sorry.
I have one of the v40's in my lab with 4 of the 875's. Very nice machine.

Does anyone know if the v20zs were dual core-capable? I heard that if you negotiate with sun (go to sun's ebay sale for the v20z), you can get really good deals. I'd love to just get two 270s if/when the prices come down.
