Did you remember to disable the debugging features in FreeBSD 6 (WITNESS, INVARIANTS, malloc debugging)?
I commented all debugging features I could found.WITNESS and INVARIANTS for sure. How do I turn off malloc debug? I used the same practice for FreeBSD 6beta3 on amd64 yet it performed actually extremely well. I was pleasently surprised with the results for 64bit mode.
If not, you're incurring a significant (usually >30%) performance penalty, which is consistent with your numbers.
Not sure about malloc stuff, but usual things were commented out. Can check kernel configs when I come back and post diffs to GENERIC here.
