I read in Unix Today! that the new IBM RISCs used an improved MCA bus
that doubled its performance from 20Mb/s to 40Mb/s.  There is a
separate, higher performance, bus for memory.

Isn't this quite underpowered relative to the CPU?  What sort of
swapping performance can I expect?

For comparison, the SS1's S-bus is 100Mb/s, I think.
