As spirantho said earlier, i believe the CyberGraphX V4 drivers are sucking the GVP ram right from the start and leaving me with only the 4 meg of slow zorro ram.
Ah, I overlooked that part of the conversation. There are a few things you can try to verify that. First, try booting without a startup sequence (so the CGX drivers don't get loaded) and run the benchmark again. Also try checking the priorities of your various memory nodes. I don't know if loading CGX into Zorro II RAM instead would make things any better (I suspect it won't), but you can try it by putting
this early in your startup-sequence.
