I'd like to see the same thing.  We have Sbus cards from Network Peripherals
and CMC/Rockwell.  Some benchmarking here shows the TCP performance to
be ~25Mbps (the NP card can transmit faster than the CMC card, but the
CMC card receives faster, go figure).  Our numbers are CPU bound on a Sparc2.
The SGI folks, claim ~70Mbps on their cards for Indigo's (of course, we've had our order in for several months and to date no FDDI cards have been seen from SGI).

SGI aside, many applications run in Sun environments and I would hope that
someone's doing a good implementation for the Sbus?  I just received one of
Sun's SAS cards, who knows maybe they will have better numbers.  Any additional
info on Sbus cards would be appreciated.
