Hmm, having easy access to a newly built dual quad core xeon box with 8gb of ram I'd really like to have a go at comparing the Opterons against the Xeons. But alas, it has Debian Etch installed, can't run BSD on it. Likely no comparison anyways (in favour of the Opeteron's I/O advantage), even with fixes to the context switching issue in 8.1 and later versions.
Having only recently become enamoured of Postgresql, BSD vs. Linux can wait for a while until I really have a handle on this fabulous DBMS.
Something to try
