Surely this comparison is influenced by which CPU models you are using. But,
it's true that the gnu compilers were particularly inefficient on the HP-735
I had for 5 years, giving less than 50% of the performance of HP compilers.
Recent work may have improved this situation somewhat for the newer
out-of-order execution processors, which ought not to be so dependent on a
close match between the compiler and the hardware.
