    SubjectMeasuring execution time
    Hello all,

    I'm not sure if this is the place to ask this particular question - if not,
    my apologies ....

    I am working on optimizing some software and would like to be able to
    measure how long an instruction takes (down to the clock cycle of the CPU).
    I recall reading somewhere about a kernel time measurement called a "Jiffy"
    and figured that it would probably apply to this.

    If anyone has any tips on how to figure out how to do this I'd really
    appreciate it.
