Hello - Trying to find out how much floating point operation performance
effects Postgres in general. Looking at some lower power machines that
have good integer performance but not great floating point performance,
shared FPU across cpus. If we store, but don't use in query criteria,
floating point numbers would Postgres perform the same as machine with
dedicated FPUs per cpu? Anyone have any suggestions or horror stories to
share on this topic?

Thanks!

-Nate
