I'm compiling the same thing, a full buildworld of FreeBSD 6.0/amd64. 
I'm even using the same disk/installation for all tests. (except the 
opteron). There is no i386 code here execpt the compatibility libraries.

The we're using a 32-bit compiler in some tests and a 64-bit one in 
other tests what will that show?

I'll make a run with a mfs so I can see how much that will improve things.

Please take another look at the page.
