meaning optimisation?

sure gcc is a whopper, 8c diminutive.

default gcc switches were used to compile, but not explicitly with 
-funroll-loops -fexpensive-optimizations -m686 -O3 ... et cetera.

gcc produces fat binaries and uses many tricks
but an AVL tree ain't a complex peice of code, aside from branch
optimisations and registerising pointer dereferences I see little
for the compiler to chew on.

is kfs the bottleneck? I don't know for sure, maybe there are
things I can do to tune kfs up. Perhaps naively I'm assuming
that once booted, most other things are equal. kfs doesn't seem
to use all of the unassigned RAM as a disc cache, but in this case
it wouldn't matter anyway. I realise 9 is distributed but this is
my living room setup not a lab.

if all this sounds incredibly naive, feel free to enlighten me.
