Are there any buses on classic systems that aren't woefully slow?
I remember getting a bit excited when I first fitted my BVision card, thinking "Well, it's got a local mini-pci connection to the Blizzard, I bet that should outperform a lot of the bix box amiga rivals for raw transfer speed".
Poor naive fool I was ;-) It gets about 16MB/s write speed using move16 on the 040 and about 18MB/s on the PPC (using 64-bit FPU register based transfers).
No where near fast enough for decent video streaming, or to max out the GPU with basic polygon rendering requests. Like just about every piece of hardware for any classic system, let down by dire bus performance.
Still, at least it's a bit faster than the mediator in that regard...
