8814.0. "Comparing Kernals 3.2" by SWAM1::POIANI_MI () Wed Feb 12 1997 20:13

        I am comparing kernal params between 2 machines, as I am trying to
        match up tuning that has been done. I checked sysconfigtab and
        rc.config and everything looks good.
    
        The machine I want to emulate has these params, that are not on the
    new box, both machines are running Digital UNIX 3.2.
    
        When I do sysconfig -q here are the differences:
    
        vm:
            ubc-wait-for-io = 1 (this one eludes me)
            vm-anonklshift = 17
            vm-anonklpages = 1
        (on original system not, on new build, how are they set?))
    
        io:
            select-chunk-elements = 256
            select-max-elements = 2128
        (on original system, not on new build)
    
     I also find things on the new build that don't exist on the older box,
        for example in vm everything from contig_malloc_percent = 20
    through enable-madvise-dontneed = 0, about 10 items.
