We use the programs in regression/ and measurement/ in the RTLinux 3.0
distribution to measure some aspects of the system. I'd recommend starting
there.
Linux on PowerPC latencies are good on average but can be abysmal if you're
interested in the worst-case. On a stock PowerPC desktop system from the
store one can be assured of 16-20us worst-case latencies with RTLinux 3.0
and better with embedded processors/boards.
} I am looking for some benchmarking tools for
} evaluating the performance of VxWorks/RTLinux/standard
} linux on a PowerPC machine. Actually we are planning to
} replace VxWorks with linux. I need to prove that standard
} linux/RTLinux can successfully replace VxWorks.
} Also, I need to decide whether to go for a standard
} linux or an RTLinux. Has anybody conducted some
} benchmarking of this kind on a PowerPC machine? If so,
} could you please tell me what tools did you use for this
} purpose..
