  This can tell you about the bandwidth to memory, but cache and 16 bit
memory can make an SX and DX look too close to call. You are right that
this gives useful information about system performance, however!

  Semi-related: I have a benchmark of my own devising, and on every 386
it shows that the 16 bit integer arithmetic is faster than 32, while on
486s short is slower than long. Interesting...
