My first reaction is that the code being run on the Alpha had to have
been frighteningly, perhaps even implausibly, bad to produce that vast
of a throughput difference between hardware so hugely different in speed
and capability while the problem size was still in a range the TRS-80
could handle at all. (And I suspect the problem was very carefully chosen.)
