Safety 0 currently does not mean top speed. I had to eliminate a lot
of "optimizations" to make ECL more stable, such as full unboxing of
functions and some inline forms. It can also be due to an "abuse" of
CLOS. ECL's implementation is not particularly efficient at method
dispatch. So, yes, one still has to improve a lot on performance and
it is big software like this one that may help.
