Unfortunately, it was 10x slower than the 0.3.9 version currently in the ports tree. I never got it to the same point ... after a few days, had only written about 6-10GB of data.  

It's the same as p4 (+ few minor tweaks). fuse-0.4 is more strict on
resizing files which is very likely to be slow for encrypted file
system (encfs). Try setting sysctl vfs.fuse.sync_resize=0.

I don't know all the details but there was memory leak and arbitrary
memory corruption in old fuse. It's believed to be fixed in fuse-0.4. My
guess you are hitting the same bug.
