Uh, you never actually supplied any numbers (or much of any other
specifics about what was tested, either).

My first reaction is "don't vary more than one experimental parameter at
a time".  There is no way to tell whether the discrepancy is due to the
different hardware, different Postgres version, or 32-bit vs 64-bit
build.
