5-CURRENT amd64 performance versus i386 performance on same HW

[Chad Leigh -- Shire.Net LLC]

I was wondering if anyone has done performance tests, especially  
network and disk IO tests on an opteron system, or preferably a dual  
opteron system, using the 5-CURRENT or similar codebase for both the  
amd64 release as well as the i386 release.  I am wondering how the  
amd64 codebase compares to the i386 codebase on identical HW.  This  
is for a server type use.

I have a single processor opteron that will be put into use as a  
firewall[PF]/router/vpn-gateway for a bunch of other internet servers  
and was wondering whether to go with the amd64 or the i386 versions  
of FreeBSD.  My other opteron (dual) is running i386 version as I had  
some linux and java needs which at the time I put it into service,  
was not readily available on amd64 (which may have changed by now).

Thanks
Chad
