Well, scratch that idea!
In my SE/30 with 48MHz Turbo040, with Enhanced PowerMath I get the following results: 39.8 CPU, 9.33 FPU (Norton System Info 3.5.3). With Enhanced PowerMath turned off, I get the same results.
You can really see how important memory bandwidth is to some of the tests that they're using, though. With the 128k cache turned off, my scores dropped to 30.1 CPU, 8.1 FPU. Obviously a lot of their tests fit wholly into 128k L2 cache but not into the (32k? I don't remember exactly) L1 cache.
Re: IIci with OS 8... You're totally right about the IIci loving System 6... That said, mine seems to like running OS 8.1 from time to time; it's like going window-shopping and it's glad to get back to System 6 when it can. Since it's used for testing, it's napping 99% of the time anyway.
Also, 68030 Macs run MacOS 8 just fine; the biggest problem is making sure to have enough RAM. http://home.earthlink.net/~gamba2/os8_68030.html
