Free/Open Cross-Platform SPEC Substitutes? 12
ErnstKompressor asks: "In light of the endless debate regarding top-dog performance between all flavors of OS/Hardware, the failings inherent in the various methods of testing such diverse systems, and the cost of existing software solutions, I was wondering what the Slashdot community recommends in the way of free, open-source, cross-platform, performance evaluation software. Additionally, how should one go about testing systems to obtain the fairest results? What compilers are evenly matched amongst different hardware? What balance should one strive for regarding optimizations and platform specific enhancements versus results that represent real-world performance? Finally, should such tests take into account the sub-systems available, such as 3D performance and the various Quake-FPS metrics?"

LMbench [bitmover.com] is great for testing the subsystems of different UNIX systems. It is probably one of the most useful benchmarks other than whatever applications you will actually be running.

All benchmarks are fair unless you deliberately picked the criteria to favor one candidate over the other, or overgeneralize the collected results beyond reason. The bigger question is whether they are representative or real performance in real application.
What compilers are evenly matched amongst different hardware?
Compilers are not evenly matched among different source code, nevermind different hardware. I don't see how you can
