Ok I ran some quick tests
For a Macintosh IIvx, a 32Mhz 68030, with 68882. 32K L2 cache.

"Yet another simplified code example, no I didn't want to wait a million
iterations"

Time millisecondsToRun:
    [100000 timesRepeat: [10.0+5.0/18.88*9.77-5.77]]


The 2.5 VM without 68882 support as shipped took 82319 & 80194 milliseconds

My recompiled VM with 68882 support took 63128 & 62662 milliseconds

Perhaps I'll reboot the 950 with a Mac OS and see how long it takes to run
the code example. But for now note the 950 took only 17410 & 17330
milliseconds

(The 950 being a 66Mhz 68040 with 8K L1 cache)

But of course the question really is how much floating point math do  you
do? (Another question is performance under macos and compiler, versus under
Linux and GCC)
