Re: Quadra840av Speed Freak
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. It spends 99% of it's time running NetBSD unix, and 1 percent running MacOS 7.6.1. For a bit of fun I ran speedometer. To my dismay it runs slower than the reference Quadra 840AV and I've not been able to discern what is causing this. Any ideas would be greatfully appreciated. My configuration is 2x 4.3gb IBM 7200rpm scsi drives. 128mb ram (32mb X4 @60ns) +2mb additional video ram. Test My Quad Ref Quad840av CPU:1.41 1.58 Graf: 1.88 0.81 Disk: 4.38 1.69 Math: 24.24 24.03 PR: 1.82 1.34 Next step will probably be chipping then overclocking it ..but has anyone got a clue as to why I'm getting the lower integer/instruction throughput? I went to Low End Mac to compare my results with yours -- and discovered that although I have a Q840av in my bedroom, I've never actually benchmarked it. A project for the next time I have a few spare hours The math results tell me that your 840av is running at the correct CPU speed, since it's virtually identical to the reference machine. There's about a 10% difference between the reference 840av and yours, which strikes me as odd, especially since you have 60ns RAM. There's evidently some difference in configuration between your machine and the reference one. And graphics results are even worse. Do you have Virtual Memory enabled? That could be slowing things down. Do you have Personal File Sharing enabled? That could be slowing things down. Or maybe you're using a whole different version of the Mac OS than was used on the reference system. Perhaps the other 840av was benchmarked with 7.5.x or 8.x, which might have improved graphics support.
