Good points. The kit in question is running MacOS7.6.1. Virtual memory is disabled, and file sharing is also non-enabled as an extention/control panel.
The results vary less than one percent depending if I shift-load it for extentions off. It just has me puzzled. Perhaps the reference 840av was tested with a version of MacOS that handles things a little quicker. Tried it on a friends 840av, again under 7.6.1 and he has comparable results within 2% tolerance with mine. Interestingly enough, our machines are faster than the reference lmbench 840av's under unix. (A separate benchmark suite). It has me stuffed. Would love that extra 10% performance though. One thing I was thinking of trying was yanking half the simms out and re-testing. Perhaps the m68040's have a similar trait of a blocking architecture for the ram refresh as do the Mips r4600 cpu's, in that the more ram you have the slower it runs by as much as 5%. Not sure. Anyone else have any suggestions? Alastair Boyanich --- Dan Knight <[EMAIL PROTECTED]> wrote: > On 7/20/03 3:59 PM, Alastair Boyanich posted: > > >Okay. Dilema. I have a 40Mhz Quarda 840av.
