If I recall correctly, the IIvx was crippled in that while the CPU ran at around 32MHz, the bus speed was only 16MHz.
This may have been done to preserve NuBus compatibility with older machines, but made it a real "buyer beware" machine, because the CPU clock speed did not reflect the actual performance of the machine. (Much like the Classic II: it shared the same 16MHz 68030 processor as the SE/30, but with a 16 bit bus it performed poorly by comparison).
