====== nBench ======

[[http://www.tux.org/%7Emayer/linux/bmark.html|nBench]] is a port of the BYTEmark benchmark to Linux/Unix platforms. The program measures the performance against a reference system (AMD K6/233, running Linux).

===== Results Summary =====

  * The current JIT implementation in SheepShaver is very basic and, for example, does not perform any register allocation. Rather, generic code templates are generated for each PowerPC instruction. Still, the CPU emulator on the x86-64 system performs nicely as exceeds the performance obtained on a Powerbook G4 @ 400 MHz by up to 50%.

  * Considering MacOS 9 is running natively under SheepShaver with no CPU emulation, and the testruns are long enough to leverage CPU used for other tasks like interrupt handling and video refreshing, we could explain higher results within MacOS X (by up to 30%) from better compiler optimizations. Reminder: CodeWarrior Pro 5.3 is very old.
