Thanks Charles, I will try this when I next get the chance.

Perhaps I mucked something up during the install;

I noticed that when reaming kfs with blocks smaller than 8k the
performance of the filesystem was markedly degraded and the
error "dnodebuf: trip indirect" would pop up occasionally.

Even so, I'm almost certain that it was operating on an fs
reamed with the default block size. kfs doesn't seem to be
particularly quick especially when another process is wandering
around the file tree. I just went with the defaults so I may
be missing some important tuning tricks.
