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."

yeah, definitely surprised. I just tested the liveCD and it "felt" a bit sluggish. But I thought it was just the liveCD. Any idea why?! maybe old GCC?

Slowlaris indeed ;) (*no bashing intended!*)

Some of this might very well be a GCC issue.

It would be interesting to see these tests redone using Sun's compiler instead of GCC (which can be installed using ss-dev on OpenSolaris).

GCC 3.4 is fairly ancient that's for sure. I know there is a plan to integrate 4.3 into OpenSolaris, I know I came across a package on opensolaris.org that was pre-built by someone that gave you this.

Definitely GCC. Not only it's old, it's also not 'native' to Solaris. GCC is developed and optimized for Linux. (Open)Solaris is built with Sun Studio. These benchmarks are always interresting, too bad this one is kind of spoiled by choosing incorrect compiler.

How is the compiler optimized to the OS? Can you give more details on that?

I would expect the standard library to be highly optimized, but not the compiler (optimizing only on a lower, hardware level).

Or does GCC on Solaris still use the GNU C Library in contrary to Sun's?
