Tom,
I've got one upstairs (HPPA), and I believe that it's actually a pretty
common situation in scientifically-oriented workstations from a few
years back.
Last I checked, scientific workstations aren't exactly a common platform for
PostgreSQL servers.
The question is, for our most common platforms (like AMD and Intel) is the FPU
notably slower/more contended than integer division? I'd the impression that
it was, but my knowledge of chip architectures is liable to be out of date.
Can we have a hardware geek speak up?
