There has never been a 64 bit port of CMUCL.  There is a partial port
for amd64 by Ed Wang, but it never got finished.

Alex has retired from making CMUCL for FreeBSD snapshots.  

I volunteered to take over but real life got in the way.  I don't have
any 32 bit FreeBSD installations left in my home farm.  So to build
the 32 bit binaries for various FreeBSD versions I probably need to
install a bunch of chroots, which then need the usual enter-chroot
customization blues.  I didn't do that yet.

I'll see whether I can get my behind in gear and get this going this

Interesting you have lower performance in SBCL.  Are you comparing a
64 bit SBCL with a 32 bit CMUCL? Is your SBCL binary (whichever
bitcount) compiled with thread support?
